HCV viral load in different genotypes and gender-wise genotype distribution in HCV-infected patients.

Genotypes	HCV RNA Median (IQR) (lg·IU/ml)	Gender, n (%)		χ^2	-value
		Male	Female
1b	6.25 (5.65, 6.68)	572 (52.28)	522 (47.71)	0.004	0.947
2a	5.56 (4.61, 6.11)^†	340 (48.78)	357 (51.22)	5.087	0.024
3a/b	5.86 (5.34, 6.46)^‡	69 (69.00)	31 (31.00)	11.234	0.001
