Journal ArticleDOI
Sample size calculation for stepped wedge and other longitudinal cluster randomised trials.
TL;DR: This work derives formulae for sample size for repeated cross-section and closed cohort cluster randomised trials with normally distributed outcome measures, under a multilevel model allowing for variation between clusters and between times within clusters.
Journal ArticleDOI
A simple sample size formula for analysis of covariance in cluster randomized trials
TL;DR: This work calculates the efficiency of an ANCOVA analysis using the baseline scores compared with an analysis on follow-up scores only, and suggests that analysis of covariance can substantially reduce the number of clusters needed.

TL;DR: For example, this paper proposed a hybrid before-and-after and step-wedges design for the HiSTORIC trial, which is a step-wedge trial with non-uniform correlation structure.
