In this course, you’ll learn how to design and carry out clinical trials. Each design choice has implications for the quality and validity of your results. This course provides you and your team with essential skills to evaluate options, make good design choices, and implement them within your trial. You’ll learn to control for bias, randomize participants, mask treatments and outcomes, identify errors, develop and test hypotheses, and define appropriate outcomes. Finally, a trial without participants is no trial at all, so you’ll learn the guiding principles and develop the essential skills to ethically and conscientiously recruit, obtain consent from, and retain trial participants.
