Twenty-one trials (2372 participants) met the inclusion criteria for quantitative synthesis. There were large variations in the exercise programme's content, mode of delivery, frequency and duration, participant's symptoms, duration of symptoms, outcomes measured, methodological quality and reporting. Comparator groups... | A search of medical databases up to March 2016 found 21 studies with 2372 people which considered pain, movement or both alongside psychological and social outcomes when people with pain and stiffness in their knee, hip, or both took part in exercise. Participation in exercise programmes probably slightly improves pain... |
Three trials (723 participants) were included. Only one trial used adequate outcome measures of efficacy; therefore, the results pertaining to efficacy are based on a single trial, whereas the results pertaining to adverse events are based on all three included trials. There was no overall difference in time to treatme... | In this systematic review, we summarise three studies in which oxcarbazepine and carbamazepine treatment were compared directly. We found that both drugs appear to be equally effective and to cause side effects equally often. Significantly fewer patients on carbamazepine developed nausea or vomiting during treatment. |
We included 12 randomised controlled trials involving 1471 patients. All the trials were of relatively short duration (12 weeks to six months). After treatment, patients treated with endothelin receptor antagonists could walk on average 33.71 metres (95% confidence interval (CI) 24.90 to 42.52 metres) further than thos... | Tradiational therapies for pulmonary arterial hypertension include prostacyclin and its analogues, calcium channel blockers, nitric oxide (NO), and important adjunctive therapies, such as anticoagulants and oxygen. Endothelin receptor antagonists have recently been proposed as an alternative to these traditional therap... |
We included one unpublished and seven published studies (total of 808 participants); four more studies and 478 more participants than the 2011 review. Six trials included young children aged one to four years receiving sucrose or candy lollypops for immunisation pain compared with water or no treatment. Usual care incl... | Study characteristics: We found six studies focused on young children aged one to four years; two of these studies were included in the original review and four were new studies. The two studies included in the original review used a low concentration of sucrose, just 12%, which is not considered sweet enough for the p... |
Forty one trials (n=4935 women) were included. The evidence suggested that GnRHas were more effective at symptom relief than no treatment/placebo. There was no statistically significant difference between GnRHas and danazol for dysmenorrhoea RR 0.98 (95%CI 0.92 to 1.04; P = 0.53). This equates to 3 fewer women per 1000... | Endometriosis is a common condition affecting women of child-bearing age, and is usually due to the presence of endometrial tissue in places other than the uterus. Common symptoms include pain and infertility. GnRHas are a group of drugs often used to treat endometriosis by decreasing hormone levels. This review found ... |
Five trials with a total of 924 participants met the inclusion criteria; 5% of participants were HIV positive. Only one small trial was methodologically adequate. The two largest trials (818 participants) had unclear allocation concealment and included < 90% of randomized participants in the analysis. There was no stat... | This review identified five trials involving 924 people, but none were of high quality. The review found no significant differences between rifabutin- and rifampicin-containing treatment in curing tuberculosis and preventing relapse, but higher doses of rifabutin might be associated with more adverse effects and there ... |
The updated search retrieved 535 records; we included 13 parallel-designed RCTs comparing IMSI and ICSI (four studies were added since the previous version), comprising 2775 couples (IMSI = 1256; ICSI = 1519). We are uncertain if IMSI improves live birth rates (risk ratio (RR) 1.11, 95% confidence interval (CI) 0.89 to... | We found 13 randomised controlled trials (four more than in the previous version), evaluating 2775 couples, that compared regular ICSI with IMSI for assisted reproduction. These studies were funded by fertility centres and universities. Based on the very low-quality evidence that we found, we are uncertain of the benef... |
Sixteen orlistat (n = 10,631), 10 sibutramine (n = 2623) and four rimonabant trials (n = 6365) met inclusion criteria. Attrition rates averaged 30% to 40%. Compared to placebo, orlistat reduced weight by 2.9 kg (95% confidence interval (CI) 2.5 to 3.2 kg), sibutramine by 4.2 kg (95% CI 3.6 to 4.7 kg), and rimonabant by... | This review assessed the long-term benefits and risks of approved anti-obesity drugs in clinical trials of 1 to 4 years duration. Sixteen orlistat (10,631 patients), 10 sibutramine (2623 patients) and four rimonabant (6635 patients) studies were examined. High drop-out rates (30% to 40%) were a limitation of nearly all... |
We included 15 studies from the earlier review and two new studies (17 studies, 1342 participants) in seven neuropathic pain conditions. Eight cross-over studies with 302 participants had a median of 36 participants, and nine parallel group studies with 1040 participants had a median of 84 participants. Study quality w... | In March 2015 we performed searches to look for new studies in adults with neuropathic pain of at least moderate intensity. We found only two additional small studies that did not provide any good quality evidence for either benefit or harm. This is disappointing, but we can still make useful comments about the drug. A... |
Twenty-eight studies on 907 participants were included in the review. Study sample size was generally small (range 5 to 96 people) and overall quality was generally poor due to inadequate blinding and allocation procedures. Meta-analyses were limited by heterogeneity of outcome measurement and inadequate reporting of d... | This review comprised 28 studies of 907 participants, with the quality of evidence being generally poor. Performing ACTs during an acute flare-up of COPD reduced the likelihood of needing mechanical assistance to breathe, as well as the length of time for which it was required. Time spent in hospital was slightly reduc... |
We included eight studies in the review. All outcomes were short term (less than six months). There were clear differences in a number of outcomes in favour of the yoga group, although these were based on one study each, with the exception of leaving the study early. These included mental state (improvement in Positive... | We included eight short-term studies (less than six months) that randomised people with schizophrenia to either receive sessions of yoga or standard care in this review. The yoga programmes described varied from 45 minutes to 1 hour in length, and from 8 sessions to a maximum of 36 sessions. We found these studies by e... |
One open-label, randomised, single-centre trial including 70 participants with Marfan syndrome (aged 12 to 50 years old) met the inclusion criteria. Participants were randomly assigned to propranolol (N = 32) or no treatment (N = 38) for an average duration of 9.3 years in the control group and 10.7 years in the treatm... | We included one study of 70 participants aged 12 to 50 years old with Marfan syndrome, who were assigned to either a beta-blocker called propranolol or no treatment for an average duration of 9.3 years in the control (no treatment) group and 10.7 years in the treatment group. This study was supported by grants from the... |
We included 30 RCTs (6235 women) comparing different intra-vaginal oestrogenic preparations with each other and with placebo. The evidence was low to moderate quality; limitations were poor reporting of study methods and serious imprecision (effect estimates with wide confidence intervals) 1. Oestrogen ring versus othe... | We found 30 randomised controlled trials comparing intravaginal oestrogenic preparations with one another or with placebo in a total of 6235 postmenopausal women undergoing treatment for the symptoms of vaginal atrophy. The evidence is current to April 2016. There was no evidence of a difference in the proportions of w... |
Eight RCTs (with 719 participants) were included in this update. The trials were small in size and methodological quality was poor. Viral detection was performed in 38% of participants, among whom 56% had positive results. Mortality between corticosteroids and control groups was non-significant (RR, 0.93, 95% CI 0.70 t... | The effect of hormone treatment on viral myocarditis remains controversial. The review authors conducted a thorough search of the medical literature. Eight randomised trials with 719 patients which met the inclusion criteria compared hormone treatment plus conventional therapy with no hormone. Hormone treatment did not... |
From 69 identified references, nine RCTs (6,584 patients) met inclusion criteria. Tiotropium reduced the odds of a COPD exacerbation (OR 0.74; 95% CI 0.66 to 0.83) and related hospitalisations (OR 0.64; 95% CI 0.51 to 0.82) compared to placebo or ipratropium. When applied to an annual baseline risk of 45% for exacerbat... | The evidence from the trials in the review indicates that, compared with a placebo and ipratropium, tiotropium does reduce exacerbations and related hospitalisations and improves quality of life and symptoms in people with moderately severe COPD, although the evidence with regards to decline in lung function is less cl... |
We identified 6 randomised controlled trials and 1 quasi-randomised controlled trial for inclusion in the review; the total number of participants was 392. The trials had some risk of bias because five of the trials did not blind outcome assessors to treatment allocation. The interventions included ant, bee, and wasp i... | From analysis of 7 studies, which included 392 participants, we found that this treatment reduces the chance of having a serious allergic reaction to an insect sting by 90%, a consistent finding between studies. Venom immunotherapy also significantly improves the quality of life of people who have had a serious allergi... |
Studies of prophylactic administration of protein free SS note a variable improvement in the respiratory status and a decrease in respiratory distress syndrome in infants who receive prophylactic protein free SS. The meta-analysis supports a decrease in the risk of pneumothorax (typical relative risk 0.67, 95% CI 0.50,... | The review of trials found evidence that synthetic surfactant reduced the risk of RDS in babies considered at risk. Babies who receive prophylactic synthetic surfactant have a decreased risk of RDS, pneumothorax (air in the lung cavity) and death. However, babies who receive prophylactic synthetic surfactant have an in... |
The searches identified 69 trials, of which 19 (2565 participants) met our inclusion criteria. Fifteen trials compared dornase alfa to placebo or no dornase alfa (2447 participants); two compared daily dornase to hypertonic saline (32 participants); one compared daily dornase alfa to hypertonic saline and alternate day... | We included 19 trials with 2565 people with cystic fibrosis; 15 trials (2447 people) compared dornase alfa to placebo (a dummy treatment with no active medication) or no dornase alfa treatment; two trials (32 people) compared daily dornase to hypertonic saline; one trial (48 people) compared daily dornase alfa with hyp... |
We included ten studies involving data from 944 adults, all male. Five trials involved primarily cognitive behavioural interventions (CBT) (n = 664). Of these, four compared CBT with no treatment or wait list control, and one compared CBT with standard care. Only one study collected data on the primary outcome. The lar... | We identified 10 relevant studies involving data from 944 adults, all male. Few of these studies provided information about the primary outcome of this review, which was reoffending. This was usually because studies did not collect data for a sufficiently long period outside prison or the treatment setting. Many studie... |
We included four trials, containing 2018 patients. The subjects were mostly white people (female: 26% to 56%), with a median age of 58 to 66 years. About half of them had histologically proven adenocarcinoma. Of the 2018 patients, 83% to 99% had their status measured using the Eastern Cooperative Oncology Group perform... | This review of 2018 patients, from four trials, found that adding cetuximab (a newly developed agent) to standard treatment, prolonged the survival time of advanced NSCLC patients by about 1.5 months, and deferred the progression of cancer by about 0.5 month. One year after the treatment, 45% of the patients receiving ... |
Twenty randomised trials met our inclusion criteria; 16 parallel trials (977 infants) and four cross-over trials (88 infants). No studies were blinded and the quality of evidence for outcomes assessed varied from moderate to low. We found no difference in the primary outcome, death before hospital discharge, between VT... | In a search updated to January 2017, review authors identified 20 studies for inclusion in the review. Sixteen studies (977 infants) compared two separate groups of infants treated with a volume-targeted mode of ventilation compared with a pressure-limited mode of ventilation. In four studies (84 infants), the infants ... |
Eleven studies (672 participants) were included in the review. Four studies assessed the efficacy of single doses of various opioid and non-opioid analgesics; a pooled analysis of these studies was not performed but in each study opioids reduced pain more than placebo. There were no differences between analgesic drugs ... | There were no studies in people with rheumatoid arthritis that looked at the effects of weak opioids taken for more than six weeks. There were not enough studies of strong opioids to draw conclusions about their effects in rheumatoid arthritis. What is rheumatoid arthritis and what are opioids? When you have rheumatoid... |
We included 32 RCTs with 2844 adult participants. Twenty-six assessed upper-limb and six assessed lower-limb blocks. Seventeen compared ultrasound with peripheral nerve stimulation (PNS), and nine compared ultrasound combined with nerve stimulation (US + NS) against PNS alone. Two studies compared ultrasound with anato... | The evidence is current up to 27 August 2014. We found 32 studies with 2844 participants. Most studies compared ultrasound with electrical nerve stimulators or compared ultrasound combined with nerve stimulators against nerve stimulators alone. We reran the search in May 2015. We will deal with the 11 studies of intere... |
We identified one eligible study that examined the effect of computerised cognitive training (CCT) in 6742 participants over 50 years of age, with training and follow-up duration of six months. We considered the study to be at high risk of attrition bias and the overall quality of the evidence to be low. Researchers pr... | We found that a lot of shorter studies had been conducted, but only one study met our criteria for this review. It took place in the UK and included two different types of online cognitive training. The control group participated in an online game that was not expected to have cognitive effects. This training lasted si... |
We included two studies with a total of 40 participants in the review. Exercise-based CR consisted of aerobic or resistance training or both three times per week for six to eight weeks. Exercise intensity was 50% of oxygen consumption (VO2) reserve, or ranged from 60% to 80% of heart rate reserve. Two serious adverse e... | We assessed the quality of the evidence for quality of life as very low due to the young age of the participants, Insufficient blinding, small number of participants, and imprecision because of wide range of confidence intervals. The effects of exercise-based CR for people with implantable VADs were not clear. The curr... |
Four randomised controlled studies met the inclusion criteria for this review, involving a total of 302 participants lasting from 29 days to 13 months; 14 studies were excluded. The included studies differed in terms of CFTR gene replacement agent and study design, which limited the meta-analysis. One study only enroll... | We found four studies with 302 people to include in this review. The studies lasted from 29 days to 13 months. Three of these studies included both men and women aged 12 years and over and one study only included adult men. The studies compare gene therapy to a dummy treatment (placebo) both of which are inhaled as a m... |
Five studies met the review entry criteria (5537 adults). Study populations entered the studies having previously been treated with inhaled steroids and had moderate or mild airway obstruction (mean FEV1 predicted between 65% and 84% at baseline). Most of the studies assessed treatment over a period of six months. The ... | This systematic review examined randomised controlled trials comparing two commonly available combinations administered at a fixed dose through a single inhaler, fluticasone/salmeterol and budesonide/formoterol. We included five studies which recruited 5537 people. The trials were generally well designed but only recru... |
Thirty-nine studies examined the effect of printed educational materials for physicians, audit and feedback, educational meetings, educational outreach visits, financial and healthcare system changes, physician reminders, patient-based interventions and multi-faceted interventions. These interventions addressed the ove... | Research has shown that physicians in the community (in doctors' offices and clinics) can be partly to blame for resistant bacteria. Studies have shown that physicians inappropriately prescribe antibiotics for infections caused by viruses (such as the common cold). They also prescribe antibiotics that kill a wide varie... |
We identified 27 studies (1549 participants) that were eligible for inclusion. These studies provided no data relating to aldosterone antagonists in addition to ACEi or ARB (or both) on patient-level outcomes including major cardiovascular events and mortality and progression to end-stage kidney disease (ESKD) requirin... | This review of available trials showed that adding aldosterone antagonist treatment to standard therapy reduced protein release into the urine and lowered blood pressure but had uncertain effects on kidney function and survival. Treatment also increases the amount of potassium in the blood which may require treatment c... |
Individual participant data were available for 480 out of a total of 517 participants (93%), from two out of three included trials. For remission outcomes, a HR of less than one indicated an advantage for phenytoin; and for first seizure and treatment failure outcomes, a HR of less than one indicated an advantage for o... | We assessed the evidence from three studies (specifically, randomised controlled trials) comparing oxcarbazepine with phenytoin. We were able to combine information for 480 people from two of the three trials. For the remaining 37 people from one trial, information was not available to use in this review. The evidence ... |
No trials comparing hydroxyurea with placebo or standard care were found. However, we included one randomised controlled trial (n = 61) comparing 20 mg/kg/day with 10 mg/kg/day of hydroxyurea for 24 weeks. Both haemoglobin and foetal haemoglobin levels were lower at 24 weeks in the 20 mg group compared with the 10 mg g... | We did not find any randomised controlled trials (where people taking part in the trial have equal chances of being in the treatment or the control group) comparing hydroxyurea with a placebo (a dummy drug) or usual care. However, we found one randomised controlled trial comparing two different doses of hydroxyurea (10... |
While five studies addressed the interventions of interest, we did not include them in the review because the investigators of the studies did not report any information specific to people with cystic fibrosis. Our attempts to obtain this information have not yet been successful. We will include any provided data in fu... | Although we found five studies which looked at anti-rejection drugs, they included people with a number of chronic conditions and not just cystic fibrosis. The studies we found reported results from all volunteers combined and we were not able to isolate the results that were specific to people with cystic fibrosis. We... |
Pentoxifylline used as an adjunct to antibiotics in neonates with sepsis decreased all-cause mortality during hospital stay (typical RR 0.57, 95% CI 0.35 to 0.93; typical RD -0.08, 95% CI -0.14 to -0.01; NNTB 13, 95% CI 7 to 100; 6 studies, 416 participants, low-quality evidence). Subgroup analyses revealed decrease in... | Six randomised controlled trials met our inclusion criteria. We found low-quality evidence that pentoxifylline in combination with antibiotics decreases deaths and duration of hospital stay in newborn sepsis. Pentoxifylline treatment did not affect lung, eye, or brain injury as a result of sepsis (very low-quality evid... |
Twelve studies met the inclusion criteria recruiting 350 participants. Trial reporting was poor and trial quality was deemed inadequate to generalise findings. There was variation in the type of active and sham acupuncture, the outcomes measured and time-points presented. The points used in the sham arm of some studies... | The objective of this review was to assess whether there is evidence from randomised controlled trials that asthma patients benefit from acupuncture. The studies included in the review were of variable quality and had inconsistent results. Future research should concentrate on establishing whether there is a non-specif... |
Nine RCTs with a total of 320 participants were included. Four SSRIs were evaluated: fluoxetine (three studies), fluvoxamine (two studies), fenfluramine (two studies) and citalopram (two studies). Five studies included only children and four studies included only adults. Varying inclusion criteria were used with regard... | We found nine trials, involving 320 people, which evaluated four SSRIs: fluoxetine, fluvoxamine, fenfluramine and citalopram. Five studies included only children and four studies included only adults. One trial enrolled 149 children, but the other trials were much smaller. We found no trials that evaluated sertraline, ... |
A total of three studies including 242 participants met the inclusion criteria for this review. One study reported the diagnostic performance of CRP for two threshold levels (> 200 mg/L and > 279 mg/L) without stating the day on which the CRP was measured. One study reported the diagnostic performance of procalcitonin ... | We performed a thorough literature search for studies reporting the accuracy of CRP, procalcitonin, or LDH in identifying pancreatic necrosis. We included studies reported until 20 March 2017. We identified three studies reporting information on 242 people with pancreatitis. The studies included pancreatitis due to all... |
Six trials (1078 women) were identified for inclusion in this updated review. All six trials provided data on OS (1071 women) and PFS (1027 women). Data on resection rates and pathological response were only available for five trials (908 to 940 women) and data on recurrence were only available for four trials (737 wom... | This review found six trials that included 1078 women. Using information from the trials, we found that giving chemotherapy before surgery helped women to live longer and also to live longer without cancer. It was not clear whether chemotherapy made radical surgery easier or helped to stop the cancer from coming back. ... |
We included two interrupted time-series studies conducted in the USA. One study was conducted in five large US transportation companies (N = 115,019) that carried passengers and/or cargo. Monthly injury rates were available from 1983 to 1999. In the study company, two interventions of interest were evaluated: mandatory... | We conducted a systematic search of the literature on the effects of alcohol and drug screening among occupational drivers for preventing injury. We then appraised the quality of the studies found and assessed their results. We found two time-series studies conducted in the USA. One was conducted in five large transpor... |
Three cohort studies were eligible for analysis, including 3380 patients ; 96 children were diagnosed with CSI. One study evaluated the accuracy of the Canadian C-spine Rule and the NEXUS criteria, and two studies evaluated the accuracy of the NEXUS criteria. The studies were of moderate quality. Due to the small numbe... | We searched medical literature databases to identify studies which tested how well both decision tools can establish whether children are at risk for CSI after blunt trauma. We performed the search in February 2015. We identified three studies of moderate to good quality. All studies tested the accuracy of the NEXUS cr... |
We included seven trials, with a total of 5390 women. The quality of studies was mixed. The CS rate was slightly lower in the active management group compared with the group that received routine care, but this difference did not reach statistical significance (RR 0.88, 95% CI 0.77 to 1.01). However, in one study there... | The review included seven trials involving 5390 women. These studies show that women who received active management were slightly less likely to have a caesarean section and were more likely to have shorter labours (less than 12 hours). There was no difference in the number of assisted deliveries, nor was there any dif... |
We included 18 RCTs, which were reported in 17 publications (one publication reports on two trials) with 4342 participants (of which 212 were children) suffering from the common cold, both naturally occurring and experimentally induced. The interventions consisted of an antihistamine as monotherapy compared with placeb... | The evidence is current to August 2015. The participants were adults or children with a common cold. We excluded studies with participants suffering from hay fever, asthma or eczema. The effect of different antihistamines was compared to placebo. A beneficial effect meant a decrease in the severity or duration of the g... |
There were 1415 participants in five neoadjuvant studies and 280 participants in four adjuvant studies involving five treatment comparisons. Four of the five neoadjuvant studies collected data for the primary outcome (overall survival) and two studies had data available; one of the four adjuvant studies collected overa... | None of the studies reported data on quality of life. Many of the studies did not report information on important outcomes such as how long people will live or remain free of breast cancer. We await the publication of one relevant study involving 112 participants who receive chemotherapy before breast cancer surgery fo... |
We included data from 12 randomised trials with data for more than 11,000 women. The trials were carried out in countries across the world, and in both high- and low-resource settings. In low-resource settings women receiving usual care may have received no additional postnatal care after early hospital discharge. The ... | We included 12 randomised trials with data for more than 11,000 women. Some trials focused on physical checks of the mother and newborn, while others provided support for breastfeeding, and one included the provision of practical support with housework and childcare. They were carried out in both high-resource countrie... |
Nine randomised clinical trials were included in this review. Eight trials compared alpha blockers versus placebo (five trials tested alfuzosin and two trials tested tamsulosin, one trial tested both alfuzosin and tamsulosin, one trial tested silodosin) and one trial compared an alpha blocker (doxazosin) versus no trea... | In nine clinical trials men were either given a dummy tablet (placebo, inactive drug), an alpha blocker for one to three days (in one study up to a maximum of eight days and in another for 32 days) or no treatment before the catheter was removed. In ideal circumstances, neither patients nor doctors knew which type of t... |
Three RCTs met our inclusion criteria. The studies enrolled 151 participants with CAP or immunosuppressed patients with pulmonary infiltrates. Overall, we found that non-invasive ventilation can reduce the risk of death in the ICU, odd ratio (OR) 0.28, 95% confidence interval (CI) 0.09 to 0.88; endotracheal intubation,... | We searched the related literature and included three randomised controlled trials involving 151 adults with pneumonia aged around 60 years. We did not include patients with pulmonary tuberculosis or cystic fibrosis. We found that NIV can reduce the risk of death in the intensive care unit (ICU) and the need for endotr... |
We included five studies involving 1140 women with asymptomatic bacteriuria. We did not perform meta-analysis; each trial examined different antibiotic regimens and so we were not able to pool results. In a study comparing a single dose of fosfomycin trometamol 3 g with a five-day course of cefuroxime, there was no sig... | We included five randomized controlled trials involving 1140 women with urine test results showing asymptomatic bacteriuria. Each of the five studies looked at different antibiotics; thus, we have not pooled the results. Four of the comparisons (fosfomycin versus cefuroxime; pivmecillinam versus ampicillin; cephalexin ... |
Twenty-two trials with a total of 3529 patients are included (14 in the original review and a further eight in this update). For the majority of comparisons, only one trial was available so results were rarely combined in meta-analyses. Individual trials were generally small and risk of bias was often unclear due to li... | This review of 22 randomised clinical trials, with a combined total of 3529 patients, set out to determine if any drug was more effective than another in preventing occlusion or restenosis of the artery after the blood vessels have been surgically widened. For the majority of comparisons, only one study was available. ... |
No new trials were found for inclusion in this update. We included 24 studies; 19 including 2531 randomised participants and five including 4354 cluster-randomised participants. There were no cases of meningococcal disease during follow-up in the trials, thus effectiveness regarding prevention of future disease cannot ... | Data from 24 studies, most of high quality, including 6885 participants found that rifampin (also known as rifampicin), ciprofloxacin, ceftriaxone and penicillin are effective agents for eradicating carriage of N meningitidis. However, the use of rifampin may have a disadvantage as development of resistance to the anti... |
One study (4155 women at less than 20 weeks' gestation) met the inclusion criteria. The intervention group (2058 women) received infection screening and treatment for bacterial vaginosis, trichomonas vaginalis and candidiasis; the control group (2097 women) also received screening, but the results of the screening prog... | In this review, only one study of moderate quality evidence was included. The study reported on 4155 women randomly assigned either to an intervention group (2058 women received infection screening and treatment for bacterial vaginosis, trichomonas vaginalis and candidiasis) or a control group (2097 women received scre... |
We found no randomised controlled trials for inclusion in this review. As we did not identify any randomised controlled trials for inclusion in this review, we are unable to comment on implications for practice. Although evidence from animal studies has supported a fetal neuroprotective role for creatine when administe... | We found no completed (or ongoing) randomised controlled trials that assessed whether creatine given to the mother at times of known, suspected, or potential fetal compromise during pregnancy helps to protect the baby's brain. Randomised controlled trials are needed to establish whether creatine can protect against bra... |
Fourteen trials were identified, of which 10 trials (792 patients) were included. Four trials are awaiting assessment. In the 10 included trials follow up was performed at 14 to 35 days after stroke. In all studies neurological outcome was assessed but none of them reported on disability (activities of daily living fun... | This review identified all randomised or quasi-randomised trials of Ginkgo biloba extract in patients with acute ischaemic stroke. There was no convincing evidence, from trials of sufficient methodological quality, to support the routine use of Ginkgo biloba extract to promote recovery after stroke. High-quality and la... |
We identified 11 trials (800 participants) and two ongoing studies. Style and duration of yoga differed between trials. Half of the participants recruited to the studies were at high risk of CVD. Most of studies were at risk of performance bias, with inadequate details reported in many of them to judge the risk of sele... | We searched scientific databases for randomised controlled trials (clinical trials where people are allocated at random to one of two or more treatments) looking at the effects of yoga on adults at high risk of developing CVD. We did not included people who had already had CVD (e.g. heart attacks and strokes). The evid... |
We included 18 studies, although we were only able to extract participant data from 14 studies that included a total of 511 participants; 419 participants were managed by intralesional treatment and 92 underwent a wide resection. We were not able to extract participant data from four studies, including 270 participants... | We identified 14 studies that were suitable for analysis with a total of 511 participants; 92 were treated by wide resection compared to 419 by intralesional treatment. Age of the participants varied from 13 to 82 years with a mean age of 48 years. Women outnumbered men in the studies by just over one and a half times,... |
In this update we identified 14 additional trials resulting in the inclusion of 18 small trials in 813 patients. Eleven trials used TENS, four interferential current stimulation, one both TENS and interferential current stimulation, and two pulsed electrostimulation. The methodological quality and the quality of report... | - There was no difference in the number of people who dropped out of the trial because of side effects (difference of 0%). This could be the result of chance. Side effects - 15 people out of 100 who used electrostimulation experienced side effects (15%). - 15 people out of 100 who used a fake electrostimulation machin... |
We included 13 studies enrolling a total of 468 participants. We identified two ongoing studies. All studies included adults, and two studies included both teenagers and adults. The 13 studies took place in high altitude areas, mostly in the European Alps. Twelve studies included participants with acute mountain sickne... | We included 13 studies with a total of 468 participants. Most studies included participants with mild or moderate forms of mountain sickness, and only one study included the severe neurological (disorder of the nervous system) form. Follow-up was usually less than one day. We also identified two ongoing studies. We fou... |
A total of 54 randomised controlled trials (n = 5122) were included. No strong evidence was found to indicate that fluvoxamine was either superior or inferior to other antidepressants regarding response, remission and tolerability. However, differing side effect profiles were evident, especially with regard to gastroin... | This review reports trials comparing fluvoxamine with other antidepressants for treatment of major depression. We found no strong evidence that fluvoxamine was either superior or inferior to any other antidepressants in terms of efficacy and tolerability in the acute phase treatment of depression. However, there is evi... |
We included one large, multi-institutional, prospective RCT, involving 311 participants; the risk of bias in this study was unclear. This study found that early postoperative radiotherapy was associated with an increase in time to progression compared to observation (and delayed radiotherapy upon disease progression) f... | From the literature search in September 2014, we included one randomised controlled trial, involving 311 participants, that looked at early or delayed radiotherapy given at the time of disease progression in people with LGG. This study was well-designed and reported useful data on survival, but did not include other cl... |
A total of 26 trials involving 2997 people were included, with a follow-up ranging from 3 to 24 months. Studies were conducted in 11 different countries. The mean age of the included participants was 68 years, 68% were male and the mean forced expiratory volume in one second (FEV1)% predicted value was 44.3% (range 28%... | We evaluated 26 studies in 2997 people with COPD. Overall the evidence found was of high to moderate quality. The trials were conducted in 11 different countries. The average age of participants was 68 years, 68% of participants were men and the severity of COPD on average was severe (according to lung function measure... |
Analyses were based on 491 patients from six trials, representing 90% of all patients randomised in cisplatin-based combination chemotherapy trials and 66% of patients from all eligible trials. The power of this meta-analysis is clearly limited. The overall hazard ratio for survival of 0.75 (95% CI 0.60 to 0.96, P = 0.... | This review suggested that 54 out of every 100 patients who had chemotherapy after surgery were alive after three years, compared to 45 out of every 100 patients who received only surgery. Although these results are encouraging, there are not enough trials or patients for these results to be completely reliable. More r... |
We included one trial of 526 women with a twin pregnancy of two viable twins, with no known morphological abnormality, in this review. The trial compared women receiving fetal growth and Doppler ultrasounds at 25, 30 and 35 weeks' gestation to fetal growth alone. We judged the included study to be at low risk of bias h... | We searched for evidence from randomised controlled trials in August 2017. We found one multicentre study that was at low risk of bias. The study involved 526 women with healthy twin pregnancies that appeared to be normally formed on ultrasound. The women were randomised to have scans to measure either just the growth ... |
There were minimal differences identified between multi-session psychosocial interventions and standard educational interventions for both injection and sexual risk behaviour. Although it should be noted there were large pre-post changes for both groups suggesting both were effective in reducing risk behaviours. In add... | There were 35 trials on 11,867 participants that examined whether these interventions are effective in reducing sexual and injection behaviour associated with greater risk of developing HIV. There are not large differences in effectiveness between multi-session psychosocial interventions and briefer interventions. This... |
We included five trials from 14 reports, with a total of 494 participants. All included trials were individual RCTs that examined the effect of TNF-α blockers for KD. Five trials (with 494 participants) reported the incidence of treatment resistance. TNF-α blockers reduced the incidence of treatment resistance (TNF-α b... | We included trials that used TNF-α blockers as a treatment for children with KD and measured treatment resistance, cardiovascular events and side effects, such as infusion reactions and infections, or other symptoms. We found five completed studies with a total of 494 participants (most recent search for studies Septem... |
The 18 included trials tested seven comparisons in a total of 2615 mainly female and older participants with a total of 2619 fractures. All trials had methodological flaws that may affect the validity of their results. Three trials of 355 participants comparing a fixed nail plate (Jewett or McLaughlin) with the sliding... | The 18 randomised controlled trials included in this review tested seven comparisons in a total of 2615 mainly female and older participants.

There were 12 randomised controlled trials with 14 comparisons included in the review, with a total sample of 500 participants across all comparisons. Included studies were typically very small (n = 20 to 72), all except one were assessed as being at high risk of bias, and all reported short-term outcomes. For the purp... | The people in these studies ranged in age from 18 to 65 years and had pain ranging in severity from mild to substantial. They usually had about five sessions of MET, or the comparison treatment(s), over a period of about 10 days. The review authors aimed to determine if MET helped to relieve pain or increase a person's... |
The studies analysed were in two groups: those comparing anticholinergics with placebo and those comparing the combination of anticholinergics with short acting ß2 -agonists versus short acting ß2 -agonists alone. The former group had 13 studies involving 205 participants included in this review, and the latter 9 studi... | This review found that although this treatment was better than placebo, the size of the effect was rather small. When the drug was used in combination with more widely used bronchodilators (beta-agonists such as fenoterol), it did not appear to add much benefit. However, there are concerns about the quality of the stud... |
We identified 13 eligible cohort studies including 2837 participants with a hearing test after treatment with a platinum analogue for different types of childhood cancers. All studies had methodological limitations, with regard to both internal (risk of bias) and external validity. Participants were treated with cispla... | The evidence is current to September 2015.

We included two randomized controlled trials (experiments in which participants are randomly allocated to two or more interventions, possibly including a control intervention or no intervention, and the results are compared). One study... |
Five studies involving 3,070 individuals met the criteria for inclusion in the meta-analysis. All interventions for promoting use of booster seats among 4 to 8 year olds demonstrated a positive effect (relative risk (RR) 1.43; 95% confidence intervals (CI) 1.05 to 1.96). Incentives combined with education demonstrated ... | The authors found five studies involving a total of 3,070 participants. All interventions investigated by the studies were found to increase the use of booster seats, compared to the group receiving no intervention. The distribution of free booster seats combined with education on their use, had a marked beneficial eff... |
Sixteen trials were identified, including 558 participants. Eleven trials were of cross-over design. Eleven trials included only people with faecal incontinence related to liquid stool (either chronic diarrhoea, following ileoanal pouch or rectal surgery, or due to use of a weight-reducing drug). Two trials were amongs... | This review looked at drugs for the treatment of faecal incontinence. These included anti-diarrhoea drugs or laxatives to regulate stools, and drugs to try to enhance the tone of muscle around the anus which help to keep it closed. Sixteen small trials were found, including 558 participants. The review of these trials ... |
We included six studies: five small, cross-over studies with 174 participants, and one parallel group study with 170 participants. Participants were treated with levetiracetam (2000 mg to 3000 mg daily) or placebo for between four and 14 weeks. Each study included participants with a different type of neuropathic pain;... | Levetiracetam is one of a type of medicine normally used to treat epilepsy. Some of these medicines are also useful for treating neuropathic pain. We looked for clinical trials in which levetiracetam was used to treat neuropathic pain. We found six studies in 344 adult participants with six different neuropathic pain c... |
We included in the review seven studies with a total of 852 participants. The methodological quality of the included studies was generally ranked as showing low risk of bias in most domains, with the exception of one study, which did not mask participants. We were able to include data from 838 participants in the meta-... | Adults (18 years of age and older) undergoing surgical procedures, pregnant women in obstetrical labour and patients receiving postoperative pain relief. The evidence is current to September 2013. We found seven studies with a total of 852 participants. The maximum time that a participant was followed by the doctor was... |
Eleven studies with 818 infants met the criteria for inclusion in this review. Four trials with 329 infants assessed the use of an H2 receptor antagonist for prevention of upper gastrointestinal bleeding in high-risk newborn infants. Meta-analysis of these four trials identified a reduction in any upper gastrointestina... | We included randomised controlled trials (RCTs). The search is up to date as of 12 July 2018. We found 11 trials with 818 infants. We considered no trial to be at low risk of bias. Four trials included 329 infants in neonatal intensive care units and used a histamine 2 receptor antagonist for prevention of upper gastro... |
The database search identified 3,253 references. Sixteen trials fulfilled the inclusion criteria. Psychological interventions show a small beneficial effect on depression compared to usual care (range of SMD of depression scores across trials and time frames: -0.81;0.12). Based on one trial per outcome, no beneficial e... | This review examined clinical trials on psychological treatments and antidepressant drugs in depressed patients with coronary artery disease. The objective was to determine the effects of these treatments on depression, death rates, cardiac events such as another heart attack or surgeries, healthcare costs and quality ... |
One trial assessing smoking cessation advice for 94 infertile women smokers fulfilled the criteria for this review, but the trial did not report on the review's primary outcome of live birth or any other fertility-related outcomes. This trial of women attending a fertility clinic showed that smoking cessation advice ta... | There is no evidence from randomised controlled trials regarding the effects of preconception advice on the chances of a live birth in subfertile people. Infertility is a prevalent problem and has significant consequences for individuals, families and the wider community. People's chance of having a healthy, live birth... |
This is a substantive update of a previous review. We identified 16 additional studies for the 2018 update. We include 42 RCTs (7935 women). The aromatase inhibitor letrozole was used in all studies.

Our review includes 42 RCTs with 7935 women. In all trials the aromatase inhibitor used was letrozole. Comparators included CC, which was used in 25 of the ... |
Two trials (involving 59 mothers) that examined the use of domperidone in a total of 59 mother-infant pairs met the inclusion criteria. Meta-analysis of these trials showed a modest increase in expressed breastmilk (EBM) of 99.49 mL/day (95% confidence intervals -1.94 to 200.92; random-effects, T² 3511.62, I² 63%) in m... | Trials of medications used to improve the breastmilk supply in mothers who have insufficient milk for their hospitalised preterm infants' needs have been reported in two randomised controlled studies involving 59 mothers. These two studies gave the women domperidone 10 mg three times a day when mothers had insufficient... |
We included 11 studies that looked at diagnostic accuracy of one or two index tests: four studies (277 suspected fractures) looked at CT, five studies (221 suspected fractures) looked at MRI and six studies (543 suspected fractures) looked at BS. Four of the studies made direct comparisons: two studies compared CT and ... | We conducted a thorough search of electronic databases, trial registers and conference proceedings up to July 2012. We included 11 studies in our analysis. The studies were moderate to good quality. Four studies (277 suspected fractures) looked at CT, five studies (221 suspected fractures) looked at MRI and six studies... |
For this update we added 14 new included studies (3489 participants), and excluded four studies. We also identified 20 additional reports of completed or ongoing studies that have not been published in full. The earlier review included 47 studies. This update included 61 studies. Most compared topical NSAIDs in the for... | We searched medical databases for clinical trials comparing topical NSAIDs with placebo (creams or gels that do not contain a medicine) or other medicines in adults aged 16 years or older with musculoskeletal pain (typically sports injuries). The evidence is current to February 2015. This review is an update of 'Topica... |
We found no randomised clinical trials comparing PAIR versus no or sham intervention. We identified only two randomised clinical trials, one comparing PAIR versus surgical treatment (n = 50 participants) and the other comparing PAIR (with or without albendazole) versus albendazole alone (n = 30 participants). Both tria... | Two randomised clinical trials on the puncture, aspiration, injection, and re-aspiration method for patients with uncomplicated hepatic hydatid cyst were identified. One trial compared puncture, aspiration, injection, and re-aspiration with surgical treatment. The other trial compared puncture, aspiration, injection, a... |
We included four RCTs with 167 participants. Risk of bias of the included studies was high, as none of them reported method of randomization, allocation concealment or blinding. Only one trial mentioned our primary outcome of duration of anaesthesia. The mean difference in duration of anaesthesia with use of adrenaline... | Evidence is current to November 2014. We included studies in children (aged older than 28 days and younger than 18 years) and adult patients (aged 18 years or older) of either gender undergoing surgery on digits (fingers and toes) under nerve blocks using adrenaline with lidocaine. We found four eligible studies with 1... |
Out of 173 articles screened, three studies were included. There were two comparisons: chlorhexidine dressing following alcohol cleansing versus polyurethane dressing following povidone-iodine cleansing (one study); and silver-alginate patch versus control (two studies). A total of 855 infants from level III neonatal i... | Three studies (total participants: 855) fit our inclusion criteria. There were two main comparisons: i) chlorhexidine dressing and alcohol skin cleansing against standard polyurethane dressing and povidone-iodine skin cleansing (from one large study), and ii) silver-alginate patch against a control group without patch ... |
Three eligible studies were identified, all comparing the use of an FIS with a VLS. All studies were small, with only 131 participants in total across all trials. It was impossible for the intubators to be unaware of the device used, so all studies were at high risk of performance and detection bias for outcomes relate... | These scopes allow the intubator to see the airway via a camera, but no reviews have examined the use of an FIS in this situation. Intubation with an FIS is considered an advanced method, requiring training and experience; therefore it may be underused in clinical practice. We aimed to compare the safety and effectiven... |
We included four trials (4608 women), but only two studies contributed data to the review's analyses (n = 4472). The studies contributing data were assessed as of high risk of bias overall. One of these studies was cluster-randomised and conducted in a low-income country and the other study was carried out in a high-in... | We searched for evidence on 15 July 2015 and included four randomised controlled studies with 4608, women but only two of the studies had useable data. We assessed both studies contributing outcome data as being at a high risk of bias. One study compared the effect of the baby suckling immediately after birth with no i... |
Only one trial with an unclear risk of bias in the majority of domains was included in the study; the overall study quality was judged to be low. This factorial trial of 256 women compared three types of postal reminder strategies (in a total of 213 women) with usual care (no postal reminder, 43 women) and reported on ... | A single study of 256 women who had experienced GDM whether posting reminder letters to 213 women or their doctors, three months after the birth of a baby, would help to increase the number of women taking a blood glucose test compared with 43 women sent no reminder. This study showed that, compared with no reminder, a... |
Six randomised, double-blind studies between 12 and 24 weeks' long met the inclusion criteria. Five studies contributed data to the meta-analysis, assigning 2781 people with stable asthma to the comparison of interest. The definition of stable asthma and inclusion criteria varied across studies, and Global Initiative f... | We looked for studies at least 8 weeks' long that compared a group of people with stable asthma who stopped taking LABA versus a group who continued taking ICS+LABA together. We were mainly interested in determining whether stopping LABA had an effect on asthma attacks, asthma control or side effects. What did we find ... |
We identified six trials, involving 479 subjects, comparing incision and drainage of perianal abscess alone versus incision and drainage with fistula treatment. Metaanalysis showed a significant reduction in recurrence, persistent abscess/fistula or repeat surgery in favour of fistula surgery at the time of abscess inc... | This systematic review assesses randomised trials that have addressed the benefits and risks of combined treatment of perianal abscesses and fistulae. Six studies have been published on this topic. The analyses show that combined treatment reduces the risk of persistent abscess or fistula, or repeat surgery without a s... |
This review included 12 multicentre RCTs randomly assigning 9547 participants with stable COPD. All the studies were industry-sponsored and had similar inclusion criteria with relatively good methodological quality. All but one study included in the meta-analysis were double-blind and scored low risk of bias. The study... | The evidence was current to 7 April 2014. We included 12 studies involving 9547 COPD patients over a period of four to 52 weeks. These studies were sponsored by drug companies and were well designed. Both patients and the people doing the research did not know which treatment the patients were getting; although in one ... |
A total of 43 randomised controlled trials (4,364 participants) were included in this review. Very few trials provided data suitable for inclusion in a meta-analysis. Among the five trials that yielded data assessing the daily frequency of hot flushes suitable for pooling, no significant difference overall was noted in... | This review found 43 RCTs conducted up to July 2013 that included 4,084 participants with hot flushes who were close to the menopause or were menopausal. Evidence obtained is current to July 2013. Some trials reported a slight reduction in hot flushes and night sweats with phytoestrogen-based treatment. Extracts contai... |
Twenty-eight trials involving 107,362 women in seven countries are included in this updated review. Five studies involving 3,124 women did not contribute outcome data and we excluded them from the analyses. The methodological quality of the included trials was mixed, with significant numbers of studies at high or uncle... | We searched for evidence on 29 February 2016. This updated review now includes 28 randomised controlled studies involving 107,362 women. Twenty studies involving 27,865 women looked at interventions to increase the number of women who started breastfeeding, in three high-income countries (Australia, 1 study; UK, 4 stud... |
We found 41 trials (>33,000 participants) which met our inclusion criteria. Four trials, which directly compared the same intervention in stage-based and standard versions, found no clear advantage for the staging component. Stage-based versus standard self-help materials (two trials) gave a relative risk (RR) of 0.93 ... | In this review, we have compared stage-based programmes of smoking cessation with standard (unstaged) programmes, or with 'usual care', or with assessment only. We found 41 stage-based trials, covering more than 33,000 smokers, which measured quit rates at least six months after treatment. Only four of the 41 trials di... |
We identified 24 eligible trials with a total of 7279 adult participants randomised. Two studies focused on relapse prevention among smokers who had recently stopped smoking, and the remaining 22 studies were concerned with smoking cessation for smokers who wished to quit. Eleven studies were with women only and one wi... | We found 24 studies with a total of 7279 people. Two studies focused on helping those who had recently stopped smoking and the rest of the studies included current smokers who wished to quit. All the studies were conducted with adults. Eleven studies were with women only and one with men only. Most studies recruited fa... |
Ten randomised controlled trials were available for analysis. The quality of included studies was adequate, though in some trials the numbers were small and they were inadequately powered for equivalence or to detect significant differences. Comparisons were made between various modalities of treatments. There were no ... | The reviewers identified 10 trials that compare various fistula treatments against one another. There are various parameters that these procedures can be compared on, but we looked at the two most important ones, recurrence (the numbers who got the disease again) and incontinence (a worsening in the ability to control ... |
We included 141 studies that involved 15,141 participants and evaluated 122 blood biomarkers. All the studies were of poor methodological quality. Studies evaluated the blood biomarkers either in a specific phase of the menstrual cycle or irrespective of the cycle phase, and they tested for them in serum, plasma or who... | The evidence included in this review is current to July 2015. We included 141 studies involving 15,141 participants. All studies evaluated reproductive-aged women who were undertaking diagnostic surgery because they were suspected of having one or more of the following target conditions: ovarian, peritoneal or deep inf... |
A total of 24 studies met our inclusion criteria. Seventeen studies provided data for the primary analysis: six studies (434 children) included data on procalcitonin, 13 studies (1638 children) included data on CRP, and six studies (1737 children) included data on ESR (some studies had data on more than one test). The ... | We found 24 relevant studies of which 17 provided data for our primary outcome. Six studies (434 children) provided data for the procalcitonin test; 13 studies (1638 children) provided data for the C-reactive protein test, and six studies (1737 children) provided data for the erythrocyte sedimentation rate test. We fou... |
Twelve double-blind RCTs (n=700) met the inclusion criteria. The meta-analysis was done on seven studies using the total score on the Hamilton Anxiety (HAM-A) scale as a common outcome measure. The result suggests a significant effect towards a reduction of the HAM-A total score in patients receiving kava extract compa... | Twelve trials met the inclusion criteria. The meta-analysis of seven trials suggests a significant treatment effect for the total score on the Hamilton Anxiety Scale in favour of kava extract. Few adverse events were reported in the reviewed trials, which were all mild, transient and infrequent. These data imply that, ... |
We included 44 RCTs with a total of 12,284 participants (6042 in SEQ and 6242 in STT). The overall analysis showed that SEQ was significantly more effective than STT (82% vs 75% in the intention-to-treat analysis; RD 0.09, 95% confidence interval (CI) 0.06 to 0.11; P < 0.001, moderate-quality evidence). Results were hi... | We searched electronic databases and conference abstracts to identify any relevant studies. We include 44 studies, which tested and compared the cure rates of SEQ therapy against STTs. Our review covers research up to April 2015. The review indicates that before 2008 the cure rate for SEQ was higher than for STT. Howev... |
We included 12 controlled trials that recruited 982 infants. There was heterogeneity between trials for the outcome IVH, with three trials finding a significant decrease in IVH and one trial finding an increase in IVH in the group receiving phenobarbital. Meta-analysis showed no difference between the phenobarbital-tre... | The review of trials found that there was not enough evidence that postnatal phenobarbital is effective in preventing IVH. Furthermore, phenobarbital suppresses breathing in infants who are breathing spontaneously, causing a need for mechanical ventilation. |
Eighteen trials (reporting 20 study comparisons) met the review entry criteria. We report findings from 18 group comparisons where data were available (6343 participants, of whom 1692 were children). Ciclesonide versus placebo: The short duration of the included studies means that there is a lack of data with respect t... | The results from this review indicate that CIC at low to moderate doses improves lung function and reduces asthma symptoms compared to placebo, but the short duration of the studies means that there is a lack of information about the impact on asthma exacerbations. Thus the currently recommended doses of CIC of 100-200... |
The search identified three studies in which 2,261 participants were randomized to receive either ADT alone, or taxane-based chemotherapy at a dose of 75mg per square meter of body surface area at three-weekly intervals for six or nine cycles in addition to ADT. Primary outcomes Early treatment with taxane-based chemot... | The evidence is current to August 2018. We found three studies (specifically, randomized controlled trials) with a total of 2,261 people. The studies compared docetaxel (an anti-cancer drug) and hormone therapy to hormone therapy alone. Taxane-based chemotherapy in addition to hormone therapy likely improves overall an... |
This review includes eight RCTs (767 participants analysed in morning and evening arms).
