Associations between plasma nitrite concentrations and vascular function measures. Changes were determined from baseline to the 6-wk time point in FMD relative to changes in plasma nitrite concentration (A) and changes in blood pressure (SBP) (B). (C) Changes in vascular stiffness aortic PWV are plotted against changes in SBP. Associations were determined with the use of a Pearson’s correlation coefficient assessment. The data show values for n = 33 in the nitrate group and n = 32 in the placebo group for each correlation analysis. FMD, flow-mediated dilatation; SBP, systolic blood pressure. PWV, pulse wave velocity.
