Cluster-randomised controlled trial

A cluster-randomised controlled trial is a type of randomised controlled trial in which groups of subjects (as opposed to individual subjects) are randomised.^[1] Cluster randomised controlled trials are also known as cluster-randomised trials,^[2] group-randomised trials,^[3]^[4] and place-randomized trials.^[5] Cluster-randomised controlled trials are used when there is a strong reason for randomising treatment and control groups over randomising participants.^[6]
