Table 1.
Baseline 24 h urinary sodium excretion, anthropometrics and covariates per tertile of baseline 24 h urinary sodium excretion.
Table 2.
Change in BW, WC, BF and FFM per 100 mmol increase in 24 h urinary sodium excretion with and without adjustment for covariates (estimate and 95% CI).
Figure 1.
Restricted cubic splines of the association between 24 h urinary sodium excretion and change in BF and FFM.
3 knots positioned at the 10th, 50th and 90th empirical percentiles. Prediction lines presented over the empirical 5th-95th percentiles sodium excretion range. Abbreviations: BW, body weight; BF, body fat; FFM, fat free mass. The association between sodium excretion and change in BF and FFM are shown for a six-year period (1987–88 to 1993–94). Crude (Red line): No adjustments. Basic model (Blue line): Adjusted for baseline age, sex, education level, smoking, physical activity, alcohol consumption, menopausal status for women, height and baseline measure of outcome. Full model (Green line): Adjusted for variables in the basic model + baseline total energy intake and change in BW between baseline and follow-up.
