57,333 | How sensitive is the association between ozone and daily deaths to control for temperature? | Schwartz, J | 2,005 | Rationale: Air pollution has been associated with changes in daily mortality. Objectives: Generally, studies use Poisson regression, with complicated modeling strategies, to control for season and weather, raising concerns that the results may be sensitive to these modeling protocols. For studies of ozone, weather cont... | 1 |
