The performance of prognostic nomogram. Comparison of time-dependent AUC of derivation cohort (A) with validation cohort (B); Comparison of 365 days AUC of derivation cohort (C) with validation cohort (D). Calibration plots for the derivation cohort (E) and validation cohort (F) of the AF recurrence for 1-year nomogram. Decision curves for the AF recurrence for 1-year nomogram in the derivation cohort (G) and validation cohort (H). Orange solid line indicates net benefit of a strategy of treating all patients. Gray solid line indicates net benefit of treating no patients. Color solid line indicates net benefit of a strategy of treating patients for the derivation and validation cohort according to the nomogram predictions. AUC, area under the curve; AF, atrial fibrillation
