Cumulative incidence of HBsAg seroclearance (a) according to age during HBeAg seroclearance (b). The cumulative incidence of HBsAg seroclearance was 3.5, 4.7, 10.2, and 18.7% at 1, 3, 5, and 8 years after HBeAg seroclearance, respectively (a). For patients that achieved HBeAg seroclearance before 30, 31–40, 41–50, and > 50 years of age, the cumulative rate of HBsAg seroclearance was 0, 5.1, 41.7, and 22.9%, respectively, at 8 years after HBeAg seroclearance (b). P values were determined using log-rank testing
