Table 6 Conditional probability table for liver fibrosis severity with respect to special investigations

Fibronectin	Fibronectin < 150, %	Fibronectin 150-200, %	Fibronectin > 200, %
AAR	AAR (< 1)	AAR (1)	AAR (> 1)
APRI	APRI (< 2)	APRI (2-3)	APRI (> 3)
FIB-4	FIB-4 (< 2)	FIB-4 (2-4)	FIB-4 (> 4)
LF severity (0)	59	0	0
LF severity (1)	31	0	0
LF severity (2)	8	77	0
LF severity (3)	2	23	100

AAR: Alanine aminotransferase ratio; APRI: Aspartate aminotransferase to platelet ratio index; FIB-4: Fibrosis-4; LF: Liver fibrosis.
