The research team comprehensively searched the medical literature to identify published trials that reported consent rates by race and/or ethnicity. The team identified and reviewed 20 different kinds of studies involving over 70,000 patients. Most were conducted in the United States and most participants from minority groups were African Americans or Hispanics.

The researchers found only small differences in the willingness of minorities to participate compared to non-Hispanic whites. But the researchers found big differences when it came to who was asked to participate. In seven of the 17 clinical and surgical intervention studies, enrollment was offered to relatively few people in minority groups.
