Performance of methods for analyzing continuous data from stratified cluster randomized trials – A simulation study

Background: The adoption of cluster randomized trials (CRTs) with the stratified design is currently gaining widespread interest. In the stratified design, clusters are first grouped into two or more strata and then randomized into treatment groups within each stratum. In this study, we evaluated the performance of several commonly used methods for analyzing continuous data from stratified CRTs. Methods: This is a simulation study where we …
