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
High quality course ! covering important areas and detailed lectures, more and better than a mere introduction. Congrats ! My only regret : I'd have liked to hear more about NI and equivalence trials
The powerpoints and audio lectures are very clear and concise, much appreciated. I would also appreciate more exercises or reading materials, to help solidify our understanding of the topics.
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.
Great course! I was completely new to clinical trials, and now I feel that I can use what I learned to look for a job. Everything is explained very clearly. Thank you so much this course!
