The RCT should be the easiest method to identify. This design is used to test whether one health care intervention is superior to another. RCTs are most often used to test drugs, but they can be used to investigate many different types of health care interventions: surgery, vaccination, anti‐pressure sore mattresses, and health education. RCTs often compare a new treatment against the currently accepted best treatment. If there is no existing treatment, the new one is compared against a placebo (an inert substance or a dummy procedure).
