What is a Cluster Randomized Controlled Trial (Cluster RCT)?
A Cluster Randomized Controlled Trial (Cluster RCT) is a type of experimental study design used in epidemiology where groups or clusters of individuals, rather than individual participants, are randomized to different intervention arms. This design is particularly useful when the intervention is applied at the group level or when there is a high risk of contamination between individuals if they were randomized separately.
