Figure 5. Comparison of C‐statistics for the models of the present study (model 2 and model 3), electronic health record–atrial fibrillation (EHR‐AF), Cohorts for Heart and Aging Research in Genomic Epidemiology Model for Atrial Fibrillation (CHARGE‐AF), and coronary artery disease or chronic obstructive pulmonary disease, hypertension, elderly, systolic heart failure, and thyroid disease (C2HEST) in the total validation cohort population.

C‐statistics of EHR‐AF, CHARGE‐AF, and C2HEST were calculated from the total validation cohort. The original coefficients of the selected variables in EHR‐AF, CHARGE‐AF, and C2HEST were applied.
