patients died and 148 patients had recurrence. The receiver operating characteristic curve showed an optimal cutoff value of 4.33 for FIB-4 in predicting postoperative death, with 52.5% sensitivity and 71.7% specificity. A log-rank test showed that FIB-4 was significantly associated with overall survival (Fig. 1A) and disease-free survival (Fig. 1B). The 1-, 3-, and 5-year cumulative overall survival rates were 66.9%, 51.2%, and 42.1%, respectively, for the 183 patients with FIB-4
