Mean difference in systolic BP per 1 standard deviation increase in estimated Na excretion (a), estimated K excretion (b), and the estimated Na/K ratio (c) divided by sex, time-dependent age group, and time-dependent BMI. The overall estimated mean differences were adjusted for sex, intervention group, age, smoking and drinking status, physical activity, and body-mass index. Within-group differences were adjusted for the other covariates used in the adjustment for the overall differences. The results for the estimated Na/K ratio (panel C) are nearly identical to those for the spot urine Na/K ratio. BP blood pressure, Na sodium, K potassium, BMI body-mass index
