Figure 2.

Kaplan–Meier curves stratified by ablation or not for the probability of freedom from (A) primary endpoint (all-cause death or rehospitalization for worsening heart failure), (B) rehospitalization for worsening heart failure, and (C) all-cause death in the PSM-adjusted model. All P-values for the Schoenfeld residuals test were >0.05, indicating that the proportional hazards assumption was not violated for the analyses of all endpoints. CI, confidence interval; HF, heart failure; PSM, propensity score matching.
