Power difference in a χ2 test vs generalized linear mixed model in the presence of missing data – a simulation study

Abstract Background Longitudinal randomized controlled trials (RCTs) often aim to test and measure the effect of treatment between arms at a single time point. A two-sample χ2 test is a common statistical approach when outcome data are binary. However, only complete outcomes are used in the analysis...
