Area Under the ROC Curve of Four Scoring Systems to Predict Outcomes

	Area under the ROC curve ± SE (95% CI) [P value]
Score	Liver-related events	Death/liver transplantation
NAFLD fibrosis score	0.86 ± 0.03 (0.80–0.92) [<.001]	0.70 ± 0.04 (0.62–0.78) [<.001]
APRI	0.80 ± 0.03 (0.73–0.86) [<.001]	0.63 ± 0.05 (0.53–0.72) [.006]
FIB-4	0.81 ± 0.03 (0.76–0.87) [<.001]	0.67 ± 0.05 (0.58–0.76) [.01]
BARD	0.73 ± 0.04 (0.66–0.80) [<.001]	0.66 ± 0.04 (0.58–0.74) [.001]

NOTE. P value in square bracket is the comparison of the area under the ROC curve of each model with the reference line (null hypothesis) of .5.
