P values were obtained from linear regression analysis.
Abbreviations: Lib, liberal salt diet; Res, restricted salt diet.
Adjustment made for age, sex, BMI, race, and underlying disease.
The statistical significance was lost after race was added in the model.
Adjustment made for age, sex, BMI, race, underlying disease, serum cortisol, serum potassium, and urine potassium level.
