Medical innovations, from cold medicine to chemotherapy, happen with the help of clinical trials. But how do trials get started? Who pays for the research? And does who participates make a difference?

Dr. Laurel Rice talks about why clinical trials are the gold standard for medical research, how researchers make trial participation as safe as possible, and why it's crucial that studies recruit diverse groups of patients. 

Dr. Rice is a gynecologic oncologist and chair of the UW-Madison Department of Obstetrics and Gynecology.
