What are interventional studies?
Interventional studies are a specific epidemiological study type which is prospective and specifically tailored to evaluate direct impacts of treatment or preventive measures on disease. For example, a investigation of the iodine supplementation of cooking salt to prevent cretinism in a region with iodine deficiency.
