Mortality Disparity. We present the marginal probability of death at 1 day, 30-days, and 1 year if a patient is black compared to white, all other things being equal. This is the absolute percentage point difference, with 95% confidence intervals, in mortality among whites compared to blacks; thus a negative difference suggests that blacks have lower mortality than whites. AR = models including only age and race; ARC = models including age, race, and clinical condition, including being an ideal candidate for therapy (CCP quality indicators only); ARCH = models including age, race, clinical condition, being an ideal candidate, and hospital.
