Clinical trials are generally health related studies on humans that are subject to a set of rules which are established and overseen in the United States by the U.S. Food and Drug administration (FDA). For more information about the FDA see http://www.fda.gov/. The U.S. National Institute of Health (NIH) hosts a website that lists all current clinical trials, http://www.clinicaltrials.gov/.
1. Find a clinical trial that interests you and describe its design.
