Obtaining adjusted prevalence ratios from logistic regression models in cross-sectional studies.
In the last decades, the use of the epidemiological prevalence ratio (PR) instead of the odds ratio has been debated as a measure of association in cross-sectional studies. This article addresses the main difficulties in the use of statistical models for the calculation of PR: convergence problems, availability of tools and inappropriate assumptions. We implement the direct approach to estimate...

متن کاملآیا نسبت شانس برآورد مناسبی از خطر نسبی است؟
Relative risk (RR) and Odds ratio (OR) are two measures of risk which has been widely used in epidemiological studies. The cohort studies are designed to directly compute a relative risk, but the situation is somewhat more complicated in the case-control design. In these studies, the odds ratio gives a valid estimate of the effect size. There is not a serious problem if you don’t use of t...
