Retreatment hepatitis B surface antigen clearance prediction model identifies pegylated interferon alpha candidates in chronic hepatitis B

Figure 5 Kaplan-Meier validation of stratified hepatitis B surface antigen clearance rates. Significantly higher hepatitis B surface antigen clearance rates in retreatment hepatitis B surface antigen clearance prediction score (RHCP-S)-dominant group vs RHCP-S-challenge group [hazard ratio (HR) = 56.72, 95% confidence interval (CI): 16.20-198.63; P < 0.001] and RHCP-S-probable group vs RHCP-S-challenge group (HR = 11.38, 95%CI: 3.01-43.04; P < 0.001), indicating that stratification has strong discriminatory power. All comparisons Bonferroni-corrected. HBsAg: Hepatitis B surface antigen; RS-CG: Retreatment hepatitis B surface antigen clearance prediction score-challenge group; RS-PG: Retreatment hepatitis B surface antigen clearance prediction score-probable group; RS-DG: Retreatment hepatitis B surface antigen clearance prediction score-dominant group.
