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.
