Pearson χ2 comparisons between enrollment fractions within each racial-ethnic group for trials enrolling before and after implementation of the reporting requirements (2011-2014). Enrollment was adjusted for changes in incidence and NH-White enrollment between the periods. Significant results are listed in bold. CI, confidence interval.
