Overnight urine samples were collected on three consecutive days from 2483 persons in 12 regions of China and the mean 9-hour overnight sodium and potassium levels subsequently determined. Analysis of the data by univariate regression, simple correlation, and multiple regression indicated that there was a positive correlation between the mean level of sodium in urine and blood pressure.
