The primary outcome was the difference in the listing-to-end-stage liver disease death ratio between Black, Hispanic, and non-Hispanic White patients for each TRR. We accounted for demographics, socioeconomic status, health care access, organ availability, and transplant center competition using multivariable linear regression. We examined intra-TRR differences in waitlist composition using Levene's test of variance. Across the 66 included TRRs, Black patients had lower listing-to-end-stage liver disease death ratios than White patients in 80% of TRRs, while Hispanic patients had equal or higher listing-to-end-stage liver disease death ratios compared to White patients in 56% of TRRs. The majority of variation in racial disparities across TRRs remained unexplained by multivariable models. Disparities were attenuated after excluding patients with HCC-associated mortality. Among the 27 TRRs that contained more than one transplant center, variance across TRRs was statistically significant for Black and Hispanic waitlist composition.
