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.

Famous quotes containing the word trials:
“Misfortune is never mournful to the soul that accepts it; for such do always see that every cloud is an angel’s face. Every man deems that he has precisely the trials and temptations which are the hardest of all others for him to bear; but they are so, simply because they are the very ones he most needs.”
—Lydia M. Child (1802–1880)
