Cluster crossover and stepped wedge designs have emerged recently as study designs used in clinical and public health research settings.

The proposed research will assess the correctness of current methods and will produce a toolkit of state-of-the art, defensible trial design, analysis and reporting methods for the clinical/health researcher.
