All estimates represent pooled 2010–2014 rates. All disparities represent the absolute percentage point difference between non-Hispanic white and black patients or non-Hispanic white and Hispanic patients. IQR indicates interquartile range; CI, confidence interval; SE, standard error. A positive estimate indicates higher performance for white patients. A negative estimate indicates higher performance for black or Hispanic patients. Largest Disparity indicates the state with the largest absolute difference between white and black or Hispanic patients, while Smallest Disparity indicates the state with the smallest difference, which is often negative. The number of health centers and number of patients varies by measure, race/ethnicity, and state. See Supplemental Digital Content (eTables 9–11) for all sample sizes and for all state estimates. If a state had fewer than 100 patients in the denominator, it was excluded.

^a33 of 51 states had no statistical disparity, on average (p>=0.05)

^b26 of 51 states had no statistical disparity, on average (p>=0.05)

^c6 of 51 states had no statistical disparity, on average (p>=0.05)
