A, Effect of lower sodium intake on augmentation index (AIx). Forest plot of the effect of lower dietary sodium intake on AIx in 17 population cohorts from 14 published studies. B, Effect of lower sodium intake on central systolic blood pressure (cSBP). Forest plot of the effect of lower dietary salt intake on cSBP in eight population cohorts from six published studies. C, Effect of lower sodium intake on central pulse pressure (cPP). Forest plot of the effect of lower dietary sodium intake on cPP in seven population cohorts from five published studies. Results are expressed as mean difference (MD) and 95% confidence intervals (95% CI). Squares indicate study‐specific relative risk estimates (size of the square reflects the study‐specific statistical weight); horizontal lines indicate 95% CI; and diamond indicates the overall relative risk with its 95% CI. fHP, formerly healthy pregnant women; fPE, formerly pre‐eclamptic women; SS, salt‐sensitive participants; SR, salt‐resistant participants; YG, young participants; MA, middle‐aged participants
