Multivariable analysisa for a single procedure outcome of freedom of all atrial arrhythmias 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 | 6.55 (2.18, 19.70) | 0.0008* |
| First retreatment following a de novo PVI-only procedure vs. second retreatment | 2.86 (1.03, 7.94) | 0.0434* |
| CHADS-VASC (1-unit increase) | 0.63 (0.43, 0.92) | 0.0163 |
PVI, pulmonary vein isolation.
a
Variables with univariate P ≤ 0.20 were considered for multivariable model. Stepwise selection was used to determine variables in final model.
b
Based on overall type 3 P-values or pairwise tests (denoted by *, no adjustments for multiple comparisons were made).
