Geographic differences in the standardized HBsAg positive ratio and standardized HCV prevalence ratio in Japan. HBsAg, hepatitis B surface antigen; HCV, hepatitis C virus; NA, not available. The standardized HBsAg-positive ratio and the standardized HCV prevalence ratio are indexes taking into account of difference in age distribution of participants among regions like the standardized mortality ratio. If the standardized HBsAg-positive ratio in a region is high, it indicates that the ratio of HBsAg-positive participants to the total number of participants is high in the region. Similarly, if the standardized HCV prevalence ratio in a region is high, it indicates that the ratio of participants infected with HCV to the total number of participants is high in the region
