F2 and Sepsis: The liver transplant scoring consists of nine factors that include: post-operative serum bilirubin (0 ≤ 2.0 mg/dL, 1 = 2.0–4.0 mg/dL, 2 ≥ 4.0 mg/dL); post-operative alanine aminotransferase (ALT) (0 ≤ 40 U/L, 1 = 40–80 U/L, 2 ≥ 80 U/L); prothrombin time (0 ≤ 4 s prolonged, 1 = 4–6 s, 2 ≥ 6 s); cirrhosis, ascites, esophageal varices, and portal hypertension (0 = absent, 1 = present); and cholangitis and sepsis (0 = none, 1 = once, 2 = recurrent) [12].
