Prognostic accuracy of CLIF-C ACLF score in predicting 28-day and 90-day mortality and other diagnostic parameters for best cut-off score

Outcome	AUROC (95% CI)	Cut-off of CLIF-C ACLF	Sensitivity	Specificity	PPV	NPV
28-day mortality	0.86 (0.7–0.94)	48.5	83.3%	77.3%	74.4%	82.2%
90-day mortality	0.84 (0.7–0.96)	45.5	81%	73.7%	75.5%	79.5%

AUROC, area under the receiver operating characteristic curve; CI, confidence interval; CLIF-C ACLF, chronic liver failure-consortium acute-on-chronic liver failure; PPV, positive predictive value; NPV, negative predictive value
