The use of permutation tests for the analysis of parallel and stepped-wedge cluster randomized trials [PDF]

, 2016
We investigate the use of permutation tests for the analysis of parallel and stepped-wedge cluster randomized trials. Permutation tests for parallel designs with exponential family endpoints have been extensively studied.

Informed Consent and Cluster-Randomized Trials

American Journal of Public Health, 2012
We argue that cluster-randomized trials are an important methodology, essential to the evaluation of many public health interventions. However, in the case of at least some cluster-randomized trials, it is not possible, or is incompatible with the aims of the study, to obtain individual informed consent.
