Relationship between the fibrosis-4 test, nonalcoholic fatty liver disease fibrosis score, and the Fibrometer scores for the three risk classes (low, intermediate, and high) of the fibrosis-4 test score

Tests	FIB-4
	FIB-4 Low risk of fibrosis <1.3 (<65 years) <2 (≥65 years)	FIB-4 intermediate risk of fibrosis ≥1.3 to ≤2.67 (<65 years) ≥2 to ≤2.67 (≥65 years)	FIB-4 high risk of fibrosis >2.67	P valuea
NFS significant fibrosis (≥−1.455 in patients <65 years) (≥0.12 in patients ≥65 years)	144/1405 (10%)	125/295 (42%)	21/28 (75%)	<0.001
Fibrometer Significant Fibrosis	71/1369 (5%)	46/290 (16%)	15/28 (54%)	<0.001
