Intervention receives them
A treatment group is the set of subjects in an experiment who receive the intervention being studied—a drug, therapy, or other variable—as opposed to a control group that receives a placebo or no intervention.
Comparing outcomes between treatment and control groups reveals whether the intervention has an effect: Patients in the treatment group showed significant improvement over the control.
