WebFor meta-analysis of studies that report outcomes as binomial proportions, the most popular measure of effect is the odds ratio (OR), usually analyzed as log(OR). Many meta-analyses use the risk ratio (RR) and its logarithm because of its simpler interpretation.

This also applies to case-control studies conducted in open cohorts, which often estimate incidence rate ratios. Webwhich is the probability of healing first divided by the probability of not healing first: hazard ratio (HR) = odds = P/(1-P); P= HR/(1+ HR). A hazard ratio of 2 therefore corresponds to a 67% chance of the treated patient’s healing first, and a hazard ratio of 3 corresponds to a 75% chance of healing first”. fewest coins worksheet
