Clinical Trials
A clinical trial is a comparison test of a medication or other medical treatment, versus a placebo, other medications and devices, or the standard medical treatment for a patient's condition. Clinical trials vary greatly in size: from a single researcher in one hospital or clinic to an international multicenter trial with several hundred participating researchers on several continents. The number of patients tested can range from as few as a dozen to several thousands.
