- Clinical Research
Definition: The branch of medical science devoted to finding information that improves people's health. It includes research studies that examine the safety and effectiveness of medications, medical devices, diagnostic tests, and treatment regimens intended for human use. Usually, more than one person with the same disease is studied.
Example: For example, the Women's Health Initiative (WHI) is a national clinical research study composed of several study components. The WHI includes:
- A randomized controlled clinical trial of promising but unproven approaches to prevention;
- An observational study to identify predictors of disease; and
- A study of community approaches to developing healthful behaviors.
