Figure 3 Multivariate predictors of late atrial fibrillation (AF) recurrence as assessed by Cox regression analysis. Hazard ratios are indicated by the square points, and the 95% confidence interval (CI) is indicated by the solid horizontal lines. P values for each variable are indicated at the right. Only left atrial (LA) scarring was found to be an independent predictor, with a hazard ratio of 3.4 (95% CI 1.3 to 9.4, p = 0.01). EF = ejection fraction; HD = heart disease.
