The appropriate choice in study design is essential for the quality, execution, and interpretation of biomedical and public health research. Observational study designs, also called epidemiologic study designs, are often retrospective and are used to assess potential causation in exposure-outcome relationships and therefore influence preventive methods. Interventional studies are often prospective and are specifically tailored to evaluate direct impacts of treatment or preventive measures on disease.
