Relative changes in FE _Na (E) and u-ENaCγ (F) during inhibition of the NO system. Values are mean ± SEM. General linear model (GLM) with repeated measurements was performed for comparison within the group (δ) and interventions as between (∆) subject factor. Paired t-test or Wilcoxon signed rank test (#) was performed for comparison within treatment group at baseline vs during infusion period 90–150 min, and baseline vs post infusion 150–210 min. # p < 0.05; ## p < 0.001.
