Figure legends
Figure 1 Flow chart showing the study design. LVEF, left ventricular ejection fraction; PSM, propensity score matching; IPTW, inverse probability of treatment weighting.
Figure 2 The Kaplan-Meier curves for atrial fibrillation recurrence in patients receiving catheter ablation and medical treatment. A, the original cohort; B, after 1:1 propensity score matching; C, after inverse probability of treatment weighting. PSM, propensity score matching; IPTW, inverse probability of treatment weighting.
Figure 3 The Kaplan-Meier curves showing the cumulative incidence of primary endpoint (A), death (B), thromboembolic events (C) and heart failure hospitalization (D). TE, thromboembolism; HF, heart failure.
Figure 4 The left atrial diameter (A), left ventricular end-diastolic diameter (B), and left ventricular ejection fraction (C) of patients at baseline and the end of follow-up receiving medical treatment and catheter ablation. LAD, left atrial diameter; LVEDD, left ventricular end-diastolic diameter; LVEF, left ventricular ejection fraction.
