Table 4. Comparison of patient classification by the ELF and ELISA/HA models.

Patients with non-advanced (F0-2) or advanced (F3-4) fibrosis on biopsy were diagnosed by the ELF or ELF/HA model (specificity 80%). True negative and true positive patients identified by both tests are shaded grey; concordant and discordant misclassification rates for the 2 models are shown.

F0-2 Patients		ELISA/HA
		F0-2	F3-4
ELF	F0-2	256 71.1%	16 4.4%
	F3-4	16 4.4%	52 20.0%
F3-4 Patients		ELISA/HA
		F0-2	F3-4
ELF	F0-2	9 10.0%	8 8.9%
	F3-4	1 1.10%	72 80.0%
