The Kaplan‐Meier survival curves for freedom from atrial tachyarrhythmia after final AF catheter ablation based on the patients' CAAP‐AF scores: A, The patients were divided into six groups based on the CAAP‐AF score following the original paper.11 B, The survival curve of the patients with score 8 is separated from those with score 9‐13

The patients were divided into subgroups by using the survival classification and regression tree (CART) model to best risk stratify them for atrial tachyarrhythmia recurrence
