Rate of posthepatectomy liver failure according to risk classification based on independent risk factors in multivariable analysis

Cut-off values for independent risk factors were: remnant liver volume/body surface area less than 300 ml/m², future liver remnant plasma clearance rate of indocyanine green less than 0.075, and serum albumin concentration less than 3.5 g/dl. Low risk, no factors; moderate risk, 1–2 factors; high risk, 3 factors. *P = 0.001, †P = 0.012 (adjusted Fisher’s exact test using Bonferroni method).
