Multivariable analysis^a for a single procedure outcome of freedom of AF at 12 months

Variable or pairwise comparison, where applicable	Odds ratio (95% CI)	P-valueb
Treatment prior to enrollment:	—	0.0005
First retreatment following a de novo PVI-only procedure vs. first Retreatment following a de novo PVI + Procedure	10.9 (3.14, 37.94)	0.0002*
First retreatment following a de novo PVI-only procedure vs. second retreatment	6.6 (1.91, 22.89)	0.0028*
Ablation termination	4.7 (1.36, 16.23)	0.0144

AF, atrial fibrillation; PVI, pulmonary vein isolation.

^aVariables with univariate P ≤ 0.20 were considered for multivariable model. Stepwise selection was used to determine variables in final model.

^bBased on overall type 3 P-values or pairwise tests (denoted by *, no adjustments for multiple comparisons were made).
