Characterisation of between-cluster heterogeneity in malaria cluster randomised trials to inform future sample size calculations

Abstract Cluster randomised trials (CRTs) are important tools for evaluating the community-wide effect of malaria interventions. During the design stage, CRT sample sizes need to be inflated to account for the cluster heterogeneity in measured outcomes. The coefficient of variation (k), a measure of...
