Receiver operating characteristic (ROC) curves comparing predictive power of combined APRI/ALBI score and MELD score for postoperative outcomes

a Postoperative grade C liver dysfunction (LD), b postoperative 30-day mortality, and c LD-associated 30-day mortality. Areas under the curve: a aspartate aminotransferase/platelet ratio index (APRI) 0.640, albumin–bilirubin grade (ALBI) 0.655, APRI/ALBI 0.678, Model for End-Stage Liver Disease (MELD) 0.637; b APRI 0.647, ALBI 0.684, APRI/ALBI 0.700, MELD 0.633; c APRI, 0.651, ALBI 0.689, APRI/ALBI 0.710; MELD 0.630. For clarity, only curves for APRI/ALBI and MELD scores are shown.
