Cluster Randomized Trials - Rethinking Clinical Trials
Cluster randomized trials (CRTs) differ from individually randomized trials in that the unit of randomization is something other than the individual participant or patient.

A Primer to the Cluster Randomized Trial - PMC
Randomized clinical trials provide one of the highest levels of evidence in evaluating new therapeutics or interventions. Besides the classic parallel two-group comparisons between an experimental and a control condition, another type of randomized trial is the cluster-randomized trial (CRT).

Why and when should we cluster randomize? - ScienceDirect
A cluster randomized trial is defined as a randomized trial in which intact social units of individuals are randomized rather than individuals themselves. Outcomes are observed on individual participants within clusters (such as patients).

Cluster randomised trial - Which study type is that? A guide to study ...
A cluster randomised study (or cluster randomised trial, CRT) is an experimental design where groups or "clusters" of individuals are randomly assigned to different interventions or conditions. This approach is often used where individual randomisation isn't practical or feasible.

What type of cluster randomized trial for which setting?
Cluster randomized trials randomize entire clusters of participants to intervention conditions. This is in contrast to individually randomized trials, where individuals themselves are randomized.

How to design efficient cluster randomised trials - The BMJ
Cluster randomised trials (CRTs) involve randomisation of groups (clusters) of individuals to control or intervention conditions. 1 The CRT design is commonly used to evaluate non-drug interventions, such as policy and service delivery interventions.

How should a cluster randomized trial be analyzed?
Cluster randomized trials (CRTs) are trials in which groups, or clusters, of individuals are randomized to one of two or more conditions [1].
