Intervention – OMERACT

in a clinical trial refers to the specific treatment, procedure, or action being studied. It is what researchers administer or apply to participants to evaluate its effects on health outcomes. Participants who are randomly assigned to receive the treatment form the intervention group, which is compared against a control or comparison group to determine the intervention’s effectiveness and safety.

Synonyms: Treatment, Therapy

Example
In a randomized clinical trial testing a new diabetes medication, the intervention is the administration of the investigational drug at a specific dose. Participants assigned to the intervention group receive the new drug, while those in the control group receive a placebo. Researchers then compare blood sugar levels between the two groups to assess the intervention’s effectiveness.
