Power Calculation for Cross-Sectional Stepped Wedge Cluster Randomized Trials with Variable Cluster Sizes
Standard sample size calculation formulas for stepped wedge cluster randomized trials (SW-CRTs) assume that cluster sizes are equal. When cluster sizes vary substantially, ignoring this variation may lead to an under-powered study. We investigate the relative efficiency of a SW-CRT with varying clus...
