Urinary sodium 2-wk Mean, mmol/24-h 151.8 ± 55.7 154.3 ± 66.5 143.3 ± 53.1 Difference vs magnesium citrate 6.9 (-11.8; 25.6) 2.0 (-16.6; 20.7) .. 12-wk Mean, mmol/24-h 146.9 ± 51.2 159.8 ± 60.7 135.7 ± 45.6 Difference vs magnesium citrate 8.7 (-10.1; 27.6) 16.7 (-2.2; 35.7) .. 24-wk Mean, mmol/24-h 153.0 ± 52.6 150.4 ± 57.4 141.7 ± 45.5 Difference vs magnesium citrate 8.6 (-10.1; 27.4) 1.9 (-17.1; 20.8) .. Urinary creatinine 2-wk Mean, 12.7 ± 4.0 13.1 ± 4.2 12.6 ± 3.5 Difference vs magnesium citrate 0.1 (-0.9; 1.1) 0.1 (-0.8; 1.1) .. 12-wk Mean, 12.9 ± 3.7 13.3 ± 4.0 13.0 ± 3.6 Difference vs magnesium citrate 0.1 (-0.9; 1.0) 0.1 (-0.9; 1.0) .. 24-wk Mean, 13.0 ± 3.8 12.7 ± 3.3 12.6 ± 3.2 Difference vs magnesium citrate 0.6 (-0.3; 1.6) -0.1 (-1.1; 0.9) .. Values are mean ± SD. Adjusted mean differences (90% CIs) were obtained from linear mixed-effect models with age, sex, baseline value of the outcome of interest, time, intervention, and the interaction time × intervention as fixed effects.
