The worse outcome subgroup of patients is significantly younger (age days = 2 vs. 18, P = .02) and have more severely impaired liver function, including ALT (149.9 ± 215.4 vs. 93.8 ± 90.7, P = .05), AST (222.6 ± 272.2 vs. 131.7 ± 156.9, P = .06), ALB (24.3 ± 2.7 vs. 25.9 ± 6.1, P = .04), and jaundice (37.5% vs. 76.9%, P = .061). This evidence concerns the gene ALB and Jaundice.
