Answer this question truthfully
Confounding is a phenomenon that occurs when the relationship between a risk factor and a disease is obscured by an external variable that is associated with both the risk exposure and the disease. This external variable, known as a confounder, can make it difficult to determine whether the risk factor is truly causing the disease or if the association is due to the confounding variable. Confounding can occur in epidemiological studies and clinical trials, and it can lead to inaccurate or misleading results. To minimize the impact of confounding, researchers often use statistical techniques such as stratification or multivariable regression to adjust for the effects of confounding variables.
What is confounding, and how does it affect the relationship between a risk factor and a disease?

Answer this question truthfully
If the relative risk equals 1, it means that there is no association between exposure to a particular factor or variable and the occurrence of the disease in question. In other words, there is no difference in the likelihood of developing the disease between individuals who are exposed to the factor or variable and those who are not. The relative risk is a measure of the strength of the association between exposure and disease occurrence, and a value of 1 indicates no association.
What does it mean if the relative risk equals 1 in relation to exposure and disease occurrence?
