RE: "ESTIMATING THE RELATIVE RISK IN COHORT STUDIES AND CLINICAL TRIALS OF COMMON OUTCOMES"

Abstract

In a recent issue of the Journal, McNutt et al. (1) provided an excellent discussion of the drawbacks of the method proposed by Zhang and Yu (2). They correctly concluded that use of the log-binomial model is the correct method for estimating the relative risk in studies with common outcomes, which was the conclusion of Skov et al. (3).
