The efficiency of stepped wedge vs. cluster randomized trials: Stepped wedge studies do not always require a smaller sample size

(2013) Karla Hemming et al.   JOURNAL OF CLINICAL EPIDEMIOLOGY

Stepped wedge cluster randomized trials are efficient and provide a method of evaluation without which some interventions would not be evaluated

(2013) Karla Hemming et al.   JOURNAL OF CLINICAL EPIDEMIOLOGY

The stepped wedge cluster randomized trial always requires fewer clusters but not always fewer measurements, that is, participants than a parallel cluster randomized trial in a cross-sectional design
