Recipients in low-tier centers were younger at listing (55 years [IQR
44-62] vs 56 years [IQR 46-63] vs 56 years [IQR 47-63],
p<0.001) (Supplemental Table 3). Furthermore,
low-tier recipients were more likely to be black race (26.6% vs 21.9%
vs 20.8%, p<0.001), to have less education than a college

and to have the lowest serum bilirubin levels (0.60 mg/dL [IQR
0.4-1.0] vs 0.7 mg/dL [IQR 0.4-1.0] vs 0.7 mg/dL [IQR
0.5-1.1], p<0.001). In the high-tier programs, recipients
were more commonly blood type O (37.8% vs 37.8% vs 41.2%,
