Changes in clinical and biochemical parameters after the dietary intervention
During the run-in period two participants (one in the low sodium group and the other in the normal sodium group) had BP <90/60 mmHg and discontinued their antihypertensive medication. Another participant in the normal sodium diet group had BP consistently greater than 180/110 mmHg and his antihypertensive medication was increased to 60 mg/d. Parameters after the dietary intervention for both groups are presented in Results of the dietary interventions.SBP, systolic blood pressure; DBP, diastolic blood pressure; MAP, mean arterial pressure; Na

t-Test results from the run-in period were corrected for baseline data, and t-test results from the intervention period were corrected for run-in period data.Changes in blood pressure, serum potassium, and urinary electrolytes after the dietary intervention. Summary data of After discontinuation of potassium supplementation, serum potassium decreased similarly in both groups after the run-in period (3.18 ± 0.25 
After the run-in period, no significant differences between the low and normal sodium groups were detected for 24-h urinary sodium (93.9 ± 16.6 After the run-in period, the low and normal sodium groups showed no differences in PRA [0.60 (0.41, 1.28)
