Clinical trials are experiments designed to evaluate new interventions to prevent or treat disease in humans. The interventions evaluated can be drugs, devices (e.g., hearing aid), surgeries, behavioral interventions (e.g., smoking cessation program), community health programs (e.g. cancer screening programs) or health delivery systems (e.g., special care units for hospital admissions). We consider clinical trials experiments because the investigators rather than the patients or their doctors select the treatment the patients receive. Results from randomized clinical trials are usually considered the highest level of evidence for determining whether a treatment is effective because trials incorporates features to ensure that evaluation of the benefits and risks of treatments are objective and unbiased. The FDA requires that drugs or biologics (e.g., vaccines) are shown to be effective in clinical trials before they can be sold in the US.

DESIGN AND INTERPRETATION OF CLINICAL TRIALS からの人気レビュー
This course really helped me to understand trials and gave me starting knowledge about how to design a trial. But it is not enough itself, and you should consider taking biostatistics classes.
This course is well-designed, well-paced and well-structured. The study examples described in this course really help you understand the importance of design and interpretation of clinical trials.
Good course overall. Some information was complex and the slides were not always complete. I personally found the first 2-3 quizzes quite difficult. However, the course is useful and interesting.
I would highly recommend this course as I found it well-structured and helpful. After studying all the materials, I gained a great amount of knowledge in designing and interpretating clinical trail.
