Fig. 2: AF or AT recurrence-free rate.
From: Low-voltage-area ablation for persistent atrial fibrillation: a randomized controlled trial
a, Kaplan–Meier graph showing the primary endpoint of AF or AT recurrence-free rates after the initial ablation without antiarrhythmic drug use. b, Kaplan–Meier graph showing the secondary endpoint of AF or AT recurrence-free rates after multiple ablations without antiarrhythmic use. Comparison of the PVI + LVA-ABL group versus the PVI-alone group was performed using the two-sided, log(rank) test. The unadjusted HR and 95% CI of AF or AT recurrence in the PVI + LVA-ABL group, compared with the PVI-alone group, are also shown.
