Extended Data Fig. 1: AF/AT-recurrence-free rate with antiarrhythmic use.
From: Low-voltage-area ablation for persistent atrial fibrillation: a randomized controlled trial
a, Kaplan-Meier graph showing AF/AT-recurrence-free rates after the initial ablation with antiarrhythmic drug use. b, Kaplan-Meier graph showing AF/AT-recurrence-free rates after the multiple ablations with antiarrhythmic use. Comparison of the PVI+LVA-ABL group versus PVI-alone group was performed using the two-sided log-rank test. Unadjusted hazard ratios and two-sided 95% CIs of AF/AT recurrence in the PVI+LVA-ABL group compared with the PVI-alone group are also shown. AF/AT indicates atrial fibrillation or atrial tachycardia. AT indicates atrial tachycardia; AF, atrial fibrillation.
