eTable 3. Prevalence of classic risk factors for atrial fibrillation (e5) in men and women (nonweighted distribution in the Gutenberg Health Study).

	Variable	Men, n = 115	Women, n = 46
	Age, years	67.0 (60.3 to 71.8)	67.0 (60.0 to 72.0)
	Systolic blood pressure, mmHg	134.5±17.5	132.0±18.5
	Antihypertensive medication, n (%)	88 (76.5)	31 (67.4)
	Body mass index, kg/m2	29.2±4.7	29.6±6.7
	Cardiac failure, n (%)	50 (43.5)	28 (62.2)
	PQ interval, ms	170.8±25.1	170.8±27.2

The data shown are mean±standard deviation for continuous variables and number and percentage for categorical variables. The PQ interval is shown for persons with sinus rhythm in the study ECG and a history of atrial fibrillation
