Values are mean ± SD, or n (%) unless otherwise indicated. Baseline characteristics at the time of enrollment are shown. P values based on chi-square tests for variables with values >5, and Fisher’s exact tests for values ≤5.
AF = atrial fibrillation; CHARGE-AF = Cohorts for Heart and Aging Research in Genomic Epidemiology–AF; GED = general education development; CABG = coronary artery bypass graft; PTCA = percutaneous transluminal coronary angioplasty; TIA = transient ischemic attack.
