Summary of the performance of the liver fibrosis staging network in predicting liver fibrosis severity in the test set. The corresponding receiver operating characteristic curves can be found in Fig. 3

	Significant fibrosis (F2–F4)	Advanced fibrosis (F3–F4)	Cirrhosis (F4)
AUC	0.92 [0.86, 0.97]	0.89 [0.83, 0.96]	0.88 [0.79, 0.94]
Specificity (%; 95% CI)	91.7 [82.0, 96.8]	88.2 [77.8, 95.6]	86.5 [78.9, 94.4]
Sensitivity (%; 95% CI)	83.0 [71.7, 94.7]	79.5 [68.2, 92.5]	75.1 [56.5, 86.7]
Accuracy (%; 95% CI)	88.3 [81.5, 94.5]	85.2 [77.0, 92.0]	83.3 [76.2, 90.0]

Abbreviations: AUC = area under the curve; CI = confidence interval
