APRI for prediction of fibrosis and cirrhosis

		Sensitivity	Specificity	PPV	NPV	+ LR	− LR
Fibrosis
	APRI >0.5	47	90	80	65	4.5	0.6
	APRI >1.5	18	100	100	58	n/a	0.8
Cirrhosis
	APRI >0.5	33	73	10	92	1.2	0.9
	APRI >1.5	0	91	0	91	0	1.1

Key: positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (+LR), and negative likelihood ratio (−LR)
