Sample size calculations for stepped wedge and cluster randomised trials: a unified approach

OBJECTIVES: To clarify and illustrate sample size calculations for the cross-sectional stepped wedge cluster randomized trial (SW-CRT) and to present a simple approach for comparing the efficiencies of competing designs within a unified framework. STUDY DESIGN AND SETTING: We summarize design effect...
