Univariate analysis of total and direct bilirubin serum level for survival at 6 and 12 months.

Six month survival
Variable	Did not survive (n = 29)	Survived (n = 191)	P-value
Mean total bilirubin serum level (mg/dL)	1.54 ± 0.99 [0.3–3.75]	1.27 ± 0.70 [0.3–3.9]	0.16
Mean direct bilirubin (mg/dL)	0.58 ± 0.46 [< 0.1–1.8]	0.40 ± 0.31 [< 0.1–1.6]	0.04
12 month survival
Variable	Did not survive (n = 78)	Survived (n = 142)	P-value
Mean total bilirubin (mg/dL)	1.46 ± 0.87 [0.3–3.9]	1.22 ± 0.65 [0.3–3.9]	0.03
Mean direct bilirubin (mg/dL)	0.49 ± 0.38 [< 0.1–1.8]	0.38 ± 0.32 [< 0.1–1.6]	0.03

Variables are expressed as means ± standard deviations, followed by ranges in brackets.
