For metric variables median and inter quartile range, for categorical variables the absolute and relative frequency for each category are shown. BP: blood pressure; PP: Pulse pressure; BMI: body mass index; TC: total cholesterol; TG: triglyceride; HDL-c: high-density lipoprotein cholesterol; LDL-c: low-density lipoprotein cholesterol.

* 60 (2.67%) individuals under regular antihypertensive treatment were excluded from the assessment of systolic BP, diastolic BP and PP levels.

** Because of 229 missing value for 'smoking' and 307 missing value for 'alcohol intake', the proportions in the table were calculated based on 2022 cases for 'smoking' and 1944 cases for 'alcoholic intake'.
