Epidemiological study is a tightly controlled experiment.
An intervention is made in a clinical study under strict supervision to see how it affects a certain disease. Possible interventions include drugs, dietary restrictions, controlled diets, and exercise regimens. The intervention is delivered to the experimental group, but not to the control group.
The justification is that, as far as we are aware, clinical studies are a subset of epidemiological studies and involve carefully monitored experiments in which an intervention is used to ascertain its impact on a particular illness or condition.
Animal studies, experience trials, and case control studies are examples of studies that do not develop precisely controlled experiments. Epidemiological study is therefore the best choice.
