Legend. Model 1 also included triglycerides >102 mg/dL, creatinine >1.0 mg/dL and uric acid >4.6 mg/dL, while model 2 also included diabetes mellitus, triglycerides >99 mg/dL, creatinine >1.0 mg/dL, uric acid >4.6 mg/dL and urinary potassium >19.4 mEq/12 h. Only variables that exhibited significant association and urinary sodium excretion are presented in the table.
