Sample size requirements to detect a two- or three-way interaction in longitudinal cluster randomized clinical trials with second level randomization
BACKGROUND: When randomizations are assigned at the cluster level for longitudinal cluster randomized trials (longitudinal-CRT) with a continuous outcome, formulae for determining the required sample size to detect a two-way interaction effect between time and intervention are available. PURPOSE: To...
