ATRIAL FIBRILLATION, RECURRENCE
Based on the 7:3 ratio, 329 and 142 patients were randomly assigned into the training and testing cohorts, respectively. Baseline characteristics are summarized in Table Baseline characteristics between training cohort and testing cohortData are mean ± SD, median (IQR) or n (%)AF duration indicates time since first AF diagnosis. BMI body mass index, DBP diastolic blood pressure, SBP systolic blood pressure, AF paroxysmal atrial fibrillation, RAAS renin–angiotensin–aldosterone system, ERAF early recurrence of atrial fibrillation. *Model performance in testing cohort
