*Model 1: Adjusted for age and sex. Model 2: Additionally adjusted for education and smoking, WHR. Model 3: Additionally adjusted for SBP, DBP, blood pressure medication. All models are adjusted for operator and reader.
†β, linear regression coefficient for the difference between narcology clinic subsample and general population sample (positive value indicates higher mean in the narcology clinic subsample).
bsa, body surface area; DBP, diastolic blood pressure; SBP, systolic blood pressure; WHR, waist to hip ratio.
