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]
A randomized controlled trial (or randomized control trial; [2] RCT) is a form of scientific experiment used to control factors not under direct experimental control. Examples of RCTs are clinical trials that compare the effects of drugs, surgical techniques, medical devices , diagnostic procedures , diets or other medical treatments.
[1] [2] The crossover is in one direction, typically from control to intervention, with the intervention not removed once implemented. The stepped-wedge design can be used for individually randomized trials, [3] [4] i.e., trials where each individual is treated sequentially, but is more commonly used as a cluster randomized trial (CRT). [5]
Clinical trials units (CTU) are specialised biomedical research units which design, centrally coordinate and analyse clinical trials and other studies. Some CTUs specialise in different methodologies, such as randomised controlled trials , cluster randomised trials , surgical trials, and health services research.

Postpartum weight loss can feel impossible at times, especially if the weight isn’t coming off as quickly as you expected. But healthy postpartum weight loss is a gradual process that takes time.
Randomized, controlled, crossover experiments are especially important in health care. In a randomized clinical trial, the subjects are randomly assigned treatments. When such a trial is a repeated measures design, the subjects are randomly assigned to a sequence of treatments.
