Fig 1. Cumulative incidence of an inactive carrier according to hepatitis B virus (HBV) DNA and quantitative hepatitis B surface antigen (qHBsAg) levels in patients without cirrhosis.

Fig 1

Those with low qHBsAg and low HBV DNA levels showed higher cumulative incidence of an inactive carrier during follow-up period. A-D represent for low HBV DNA plus low qHBsAg levels (A), low HBV DNA plus high qHBsAg levels (B), high HBV DNA plus low qHBsAg levels (C), and high HBV DNA plus high qHBsAg levels (D), respectively. The cut-off level to define low vs. high was 20,000 IU/ml for HBV DNA and 2,500 IU/ml for qHBsAg.
