Distribution of patients with elevated serum Ca19.9 according to METAVIR score.

METAVIR*	Group 1	Group 2
	HCV patients (N = 60)	HBV patients (N = 31)
	N (%)	N (%)
F1–F3	26 (43.3)A	14 (45.2)B
F4	34 (56.7)C	17 (54.8)D
total	60 (51.7)E	31 (48.4)F
P values**: A vs B = ns; C vs D = ns; A vs C ≤0.05, B vs D ≤0.05  and E vs D ≤0.001

*Liver biopsy specimens were assessed by local pathologist for histology status and reviewed by one expert pathologist, blinded about specimens group assignment.

**P was calculated using a non parametric test (Mann-Whitney U test).
