Comparing the performance of different multiple imputation strategies for missing binary outcomes in cluster randomized trials: a simulation study

Although researchers have proposed various strategies to handle missing outcomes in cluster randomized trials (CRTs), limited attention has been paid to the performance of these strategies. Under the assumption of covariate-dependent missingness, the objective of this simulation study is to compare the performance of various strategies in handling missing binary outcomes in CRTs under different design settings. There are six missing data …
