Figure 2.

Incidence of atrial fibrillation after a single‐catheter ablation attempt, by left atrial (LA) fibrosis severity. A, Kaplan‐Meier cumulative incidence curve of recurrent atrial arrhythmia or repeated ablation procedure. B, The multivariable‐adjusted hazard ratio (HR) associating left atrial fibrosis (as a continuous variable) with recurrent atrial arrhythmia or repeated ablation after a single‐catheter ablation procedure. The solid line represents the HR, and the shaded area represents the 95% confidence interval. The model includes full covariate adjustment (model 4).
