A comparative blood pressure and sodium excretion were higher in Korea than in Belgium. By multiple regression and covariance analysis an independent positive association between sodium and blood pressure and a negative correlation between potassium and blood pressure were found in some population subgroups and in the total population studied in Korea. In Belgium a positive association between sodium and blood pressure was found when higher powers of age, height, weight and sodium were included in the analysis. The independent influence of sodium on blood pressure was relatively small, amounting to about 2 mm Hg of pressure rise for an increase in 24-h excretion of 100 mmol of sodium.
韩国的血压和钠排泄量比比利时更高。通过多元回归和协方差分析，在韩国研究的一些人群亚组和总人口中发现，钠与血压之间存在独立的正相关，钾与血压之间存在负相关。在比利时，当分析中纳入年龄、身高、体重和钠的高次幂时，发现钠与血压之间存在正相关。钠对血压的独立影响相对较小，24小时钠排泄量增加100 mmol时，血压升高约2 mmHg。
