Evidence-Based Medicine and the Problem of Healthy Volunteers
Journal Title: Annals of Hepatology - Year 2017, Vol 16, Issue 6
Abstract
Healthy controls are subjects without the disease being studied but may have other conditions indirectly affecting outcome. In the present epidemics of obesity a few subjects with undiagnosed nonalcoholic fatty liver disease enter clinical studies as controls, producing biased results. Stricter selection criteria should be considered to prevent this risk.
