Coronary Stent Trial Site Selection Could Narrow Racial Gaps in Enrollment, but Women Remain Underrepresented

By MedXY 04/30/2026

In nine U.S. coronary stent PMA trials, minority participants were markedly underrepresented, while women were modestly underrepresented. Site geography and surrounding county demographics predicted minority enrollment, suggesting targeted site selection could improve racial and ethnic representation.
