Fig. 1

Mean systolic BP according to quintiles of estimated urinary Na and K excretion levels (a) and the estimated Na/K ratio (b). The analyses were adjusted for sex, intervention group, age, smoking and drinking status, physical activity, and body-mass index. The results for the estimated Na/K ratio (panel B) are nearly identical to those for the spot urine Na/K ratio. BP blood pressure, Na sodium, K potassium. Vertical bars indicate 95% confidence intervals
