Getting it right: Methods for risk ratios and risk differences cluster randomized trials with a small number of clusters
Shifeng Sun, Xueqi Wang, Zhuoran Hou +1
Most cluster randomized trials (CRTs) randomize fewer than 30-40 clusters in total. When performing inference for such ``small'' CRTs, it is important to use methods that appropria…

Improving sandwich variance estimation for marginal Cox analysis of cluster randomized trials
Xueqi Wang, Elizabeth L. Turner, Fan Li
Cluster randomized trials (CRTs) frequently recruit a small number of clusters, therefore necessitating the application of small-sample corrections for valid inference. A recent sy…

Power considerations for generalized estimating equations analyses of four-level cluster randomized trials
Xueqi Wang, Elizabeth L. Turner, John S. Preisser +1
In this article, we develop methods for sample size and power calculations in four-level intervention studies when intervention assignment is carried out at any level, with a parti…
