Figure 5 Kaplan-Meier estimates of the percentages of patients remaining free of atrial fibrillation (AF) recurrence. Percentages of AF-free patients were 84%, 79%, and 78%, respectively, at one, two, and three years among ablated patients, and 61%, 47%, and 37%, respectively, among those medically treated (p < 0.001). The favorable effect of ablation on AF recurrence increased over time during the entire follow-up period, with an average risk of 0.30 (inset).
