CI, confidence interval.
†Model 1 was stratified by hospitals, and adjusted for age and sex.
‡Model 2 was stratified by hospitals, and adjusted for as model 1 plus marital status, family per member monthly income, education level, smoking status, drinking status, physical activity, and family history of stroke.
§Model 3 was stratified by hospitals, and adjusted for the variables in Model 2 plus body mass index, systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, hypotensive drug use, lipid-lowering drug use, hypoglycemic drug use, history of myocardial infarction, and snoring status.
※Model 4 was stratified by hospitals, and adjusted for the variables in Model 3 plus high sensitive C-reactive protein, and atrial fibrillation.
