Receiver operating characteristics curves for measured volume parameters in the prediction of postoperative hepatic insufficiency. sFLR, standardized future liver remnant; DH, degree of hypertrophy; and KGR, kinetic growth rate, defined as DH at first volume assessment after portal vein embolization (PVE) divided by weeks between PVE and first post-PVE volume assessment. AUC, area under the curve; CI, confidence interval; SE, standard error; p values represent asymptotic significance (null hypothesis, AUC = 0.500).
