Cluster Randomised Trials


Most evaluations involve the assessment of interventions that occur at units larger than that of individuals. These might be health system catchment areas, schools, geographic regions or even countries. In some cases it is appropriate and possible to randomly allocate the intervention of interest at the level of these larger units, and as such apply the most efficient and reliable approach to reducing confounding.
