In stepwise linear regression, we forced age, gender, body weight and body height in the model, and considered systolic and diastolic blood pressure, current smoking and drinking, the use of antihypertensive drugs, plasma glucose, and total-to-HDL cholesterol ratio as potential confounders. P value for variables to enter or stay in the model was set at <0.10. β, estimated parameter; SE, standard error; HDL, high density lipoprotein.
