Figure 2:

Association of ethnicity and incidence of AF: 5 reports from 1 country with 386,115 events. EHR – electronic health record, age range in years, follow-up in years (mean, median, or maximum), AF – atrial fibrillation, CI – confidence interval, N/23 – number (of factors) out of 23, CVD – cardiovascular disease, SD – standard deviation, NR – not reported, USA – United States of America, • – yes, ○ – no, -- – not applicable. Risk factor adjustment refers to whether adjustment was made for the 23 risk factors under review, 6 CVD risk factors, and prevalent and incident CVD events. Example: ARIC adjusted for 5/23 risk factors, age, sex, blood pressure (i. e. any of systolic blood pressure, diastolic blood pressure, hypertension, or blood pressure lowering medication), and diabetes mellitus, but not smoking or lipids (i. e. any of total cholesterol, low–density lipoprotein cholesterol, high–density lipoprotein cholesterol, triglycerides, hyperlipidaemia, or lipid lowering medication), and prevalent, but not incident CVD events.
