Comparative Effectiveness Research

The Comparative Effectiveness Research topic includes research that compares the benefits and harms of different approaches to preventing, diagnosing, treating, or monitoring health conditions. It examines options such as medicines, medical devices, treatments, and ways of delivering care in real-world settings.

People may have several care options, and their effects can vary across patients and circumstances. Direct comparisons help clarify which approaches work best, for whom, and under what conditions. This evidence can help patients, clinicians, and health systems make informed choices about care that reflect likely benefits and potential harms.
