Figure 1 Frequency distribution of the number of risk factors (male sex, HBV DNA levels >105 copies/mL [5.26 copies/mL = 1 IU mL], and the basal core promoter mutation). Among 90 inactive carriers with HBV DNA levels of 104 copies/mL or more (white bars), 39, 34, 17, and 0, respectively, had 0, 1, 2, and 3 risk factors. Among 90 patients with HBeAg-negative chronic hepatitis (black bars), 1, 13, 48, and 28, respectively, had 0, 1, 2, and 3 risk factors. The odds ratios for active hepatitis increased with the presence of an increasing number of risk factors.
