1-year AF recurrence composite outcomes for patients

	Patients	Events	Adjusted OR (95% CI)∗
Average impedance drop
High: >8.05 Ω	80	10 (12.5)	Reference
Medium: 6.47–8.05 Ω	81	17 (21.0)	1.80 (0.57–5.98)
Low: ≤6.47 Ω	81	30 (37.0)	5.91 (1.81–21.8)
Right WACA impedance drops∗
High: >8.05 Ω	74	10 (13.5)	Reference
Medium: 6.47–8.05 Ω	61	6 (9.8)	0.44 (0.09–1.79)
Low: ≤6.47 Ω	107	41 (38.3)	3.80 (1.23–13.0)
Left WACA impedance drop∗
High: >8.05 Ω	100	14 (14.0)	Reference
Medium: 6.47–8.05 Ω	75	18 (24.0)	1.50 (0.57–3.98)
Low: ≤6.47 Ω	67	25 (37.3%)	4.48 (1.57–13.5)

Values are n or n (%), unless otherwise indicated. The composite outcome includes AF hospitalization, repeat ablation, direct current cardioversion, and initialization of a new antiarrhythmic drug post–blanking period.

AF = atrial fibrillation; CI = confidence interval; OR = odds ratio; WACA = wide antral circumferential ablation.
