Comparison of Az values for the diagnosis of marked fibrosis, advanced fibrosis and cirrhosis between the intensity difference in the 15-min phase and FIB4

	For marked fibrosis (≥F2)	For advanced fibrosis (≥F3)	For cirrhosis
The intensity difference in the 15-min phase	0.88 (0.81–0.92)	0.95 (0.91–0.98)	0.97 (0.93–0.99)
FIB4	0.85 (0.78–0.91)	0.89 (0.82–0.94)	0.90 (0.81–0.96)
P-values	0.15	0.057	0.017

Az, area under the receiver operating characteristic curves; marked fibrosis, ≥F2; advanced fibrosis, ≥F3; FIB4, age × AST/(platelet count/ALT^0.5); AST (IU/L), aspartate transaminase; ALT (IU/L), alanine transaminase
