Effect of dietary sodium restriction on arterial stiffness: systematic review and meta-analysis of the randomized controlled trials.

Arterial stiffness is an independent cardiovascular risk factor and sodium intake could be a determinant of arterial stiffness. Nevertheless, the studies that investigated the effect of reducing dietary sodium intake on arterial stiffness in humans provided inconsistent results. Therefore, we performed a systematic review and a meta-analysis of the available randomized controlled trials of salt restriction and arterial stiffness to try and achieve more definitive conclusions.
