  • *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.
