Model 1 is adjusted for age, sex and race/field center. Model 2: Model 1 and additionally adjusted for education, occupation, apolipoprotein E, smoking, body mass index, systolic blood pressure, diastolic blood pressure, antihypertensive medication, total cholesterol, diabetes mellitus, prevalent coronary heart disease, heart failure, and stroke. Model 3: Model 2 and additionally adjusted for time‐dependent incident stroke and AF. All covariates except sex, race‐field center, education, occupation, and apolipoprotein E are time‐varying variables. aIAB indicates advanced interatrial block; aPWA, abnormal P‐wave axis; PPWD, prolonged P‐wave duration; PTFV1, the terminal force of the P wave in ECG lead V1.
