Aldosterone concentrations in relation to tVNS treatment
In the young cohort, aldosterone concentrations decreased significantly from pre- to post-stimulation after active tVNS (β = − 1.610 (− 2.855, − 0.365), p = 0.022) and not significantly after sham treatment (β = − 0.857 (− 2.102, 0.388), p = 0.257) (Table Shown are means ± standard deviations of the non-transformed [pg/ml] and Yeo-Johnson-transformed aldosterone concentrations for the younger and older cohort.Estimated β-coefficients are presented with the corresponding 95% confidence interval (95%CI) based on the Yeo-Johnson-transformed data.Boxplots of untransformed aldosterone concentrations before (pre) and after (post) intervention.
