Serum total bilirubin values (umol/dl) at 6, 12, 18, 24, and 36 months in recipients of livers from carriers versus noncarriers of the class short allele. a Recipients of liver allografts carrying at least one class short allele had significantly lower serum total bilirubin levels compared with recipients of allografts carrying nonclass short-allele at months of 6, 12, 18, 24, and 36 (p < 0.01). b When the time of cold ischemia time was ≥10 h, a substantial lower serum bilirubin level in recipients of short-carrier allografts than recipients of non-short-carrier grafts at months of 6, 12, 18, 24, and 36 was observed (p < 0.01). However, serum bilirubin levels in recipients of liver allografts from short-carriers that were exposed to <10 h of ischemia were not significantly different from those of recipients of allografts from long homozygotes. c In recipients of short-carrier allografts, cold ischemia time (<10 h or ≥10 h) did not affect the total bilirubin level significantly. But in recipients of allografts from long homozygotes, cold ischemia time dramatically influenced the total bilirubin level. S short, L long
