a Kaplan–Meier estimates of overall survival in patients with or without post-hepatectomy liver failure (PHLF) defined by the International Study Group of Liver Surgery (ISGLS). Grade A and grade B/C PHLF had a median survival and 5-year overall survival of 34 months (95 per cent c.i. 26 to 44 months) and 36 per cent for grade A and 18 months (95 per cent c.i. 14 to 26 month) and 24 per cent respectively, for grade B/C (log rank test, P = 0.006). No PHLF resulted in a median survival of 47 months (95 per cent c.i. 41 to 57 months) and 5-year overall survival of 45 per cent. b Kaplan–Meier estimates of overall survival in patients with or without PHLF according to the ‘50–50 criteria’ defined by Balzan et al. No PHLF had a median survival and 5-year overall survival of 42 months (95 per cent c.i. 35 to 47 months) and 41 per cent respectively, and PHLF according to the ‘50–50’ criteria had a median survival and 5-year overall survival of 10 months (95 per cent c.i. 4 to 38 months) and 26 per cent (log rank test, P < 0.001).
