A properly planned and executed clinical trials is a powerful experimental technique for assessing the effectiveness of an intervention. We consider clinical trials experiments as the investigators rather than the patients or their doctors select the treatment the patients receive. The results of randomized clinical trials usually provide the highest level of evidence to determine whether a treatment is effective. That’s because clinical trials incorporate features to ensure that the benefits and risks of treatments are objectively and unbiasedly evaluated.
