Physical characteristics and life styles of the study subjects according to the sodium intake
1) Low: Na < 4231.7 mg, Medium: 4231.7 ≤ Na < 5573.9 mg, High: Na ≥ 5573.9 mg
2) Mean ±SD
3) Hypertension: Systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg
ab: Means not sharing the same superscript are significantly different at p < 0.05 by Duncan's multiple range test
*: p < 0.05, **: p < 0.01, ***: p < 0.001 by one-way GLM
Urine volume and urinary Na, K, Ca, Mg, Creatine excretion
