In a randomized trial, which group receives the intervention?

Explanation:
The key idea is identifying who actually gets the treatment being tested. In a randomized trial, the group that receives the intervention under study is the experimental group, also called the treatment group. Other groups exist to serve as comparisons: the placebo group gets an inactive substitute to account for psychological or expectations effects, while the waiting list or standard care group does not receive the new intervention during the study period. So, the experimental group is the one that receives the intervention.
