Cluster randomized trials (CRTs) are studies where groups of people, rather than individuals, are randomly allocated to intervention or control. While these type of designs can be appropriate and useful for many research settings, care must be taken to correctly design and analyze them. This talk will give an overview of cluster trials, and various methodological research projects  on cluster trials that I’ve been undertaken: designing CRTs, the use of GEE with small number of clusters, handling missing data in CRTs, and analysis using mixed models. I will demonstrate methods with an example from a recently completed trial on reducing cardiovascular risk among Mexican diabetics.
