intervention studies

Intervention studies are research investigations designed to evaluate the effects of a specific treatment or action on a group of people. In these studies, researchers actively apply an intervention, such as a new medication, educational program, or lifestyle change, to see how it influences outcomes compared to a control group that does not receive the intervention. This allows scientists to determine whether the intervention is effective and to measure its impact on health or behavior over time. These studies are essential in advancing medical and social knowledge by providing evidence-based results.
