Table 4. AUROCs of APRI and FIB-4 for significant fibrosis and cirrhosis in patients < 30 years.

	Significant fibrosis		Cirrhosis
	AUROC	(95% CI)	AUROC	(95% CI)
APRI	0.61	(0.54-0.67)	0.64	(0.58-0.70)
FIB-4	0.57	(0.50-0.63)	0.63	(0.57-0.69)
Comparison of AUROC
APRI vs FIB-4	p=0.11		p=0.853

APRI, aspartate transaminase to platelet ratio index; FIB-4, fibrosis index based on the 4 factors; AUROC, the area under the receiver operating characteristic curve; CI, confidence interval.
