Association between smoking status and SBP (in the model adjusted for age, BMI, estimated daily salt intake, GGT, drinking status, estimated 24-h potassium excretion, physical activity, education status, damage to the home during the GEJE, and residential area). p for difference was derived from Dunnett’s test using never smoke as the reference. Bars represent 95% confidence intervals. p for difference is shown as follows: *p < 0.05, **p < 0.01, and ***p < 0.001.
