Comparison with other studies
Hg lower mean systolic blood pressure
Our results showed that the reduction in urinary sodium excretion was accompanied by a decrease in blood pressure, especially systolic blood pressure. A recent meta-analysis of randomised salt reduction trials found that every 100 mmol/day (2.3 g/day) reduction in urinary sodium excretion was associated with a 5.56 (95% confidence interval −4.52 to −6.59) mm Hg lower mean systolic blood pressure and a 2.33 (−1.66 to −3.00) mm Hg lower mean diastolic blood pressure.
