Interventional studies are crucial for several reasons:
1. Establishing Causality: By manipulating the exposure, researchers can better infer a causal relationship between the exposure and the outcome.
2. Evaluating Interventions: These studies are essential for assessing the efficacy and safety of new treatments, drugs, or public health interventions.
3. Policy Making: The results from well-conducted interventional studies can inform policies and guidelines for clinical practice and public health initiatives.
