Association between GGT levels and SBP (in the model adjusted for age, BMI, estimated daily salt intake, drinking status, smoking 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 GGT < 25.0 IU/L 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. p for trend was calculated by scoring the GGT categories and entering the number as a continuous term in the regression model.
