Kaplan–Meier disease-free survival curves and ROC curves for early recurrence. a, b and c Two-year Kaplan–Meier disease free survival curves according to RAM, ALBI and MELD classifications (P < 0.001, P < 0.001 and P = 0.158, respectively). d ROC curves of RAM, ALBI and MELD scores for predicting early recurrence (AUC =0.611, 0.582, and 0.527, respectively; RAM vs. ALBI, P = 0.057, RAM vs. MELD, P = 0.002). For RAM score, when cutoff score was 3.5, the sensitivity and specificity for early recurrence was 0.609 and 0.573, respectively. For ALBI score, when cutoff score was −2.755, the sensitivity and specificity for early recurrence was 0.485 and 0.651, respectively. For MELD score, when cutoff score was 7.5, the sensitivity and specificity for early recurrence was 0.502 and 0.545, respectively
