Differential CpG methylation is associated with reduced norepinephrine levels in non-responders to RDN. (A) ELISA analysis of EDTA plasma samples. Levels of blood norepinephrine (NE) were measured in plasma samples by ELISA, n = 5 for responders and n = 5 for non-responders to RDN, p < 0.05. Error bars show standard error of mean.
(B) Significant inverse correlation between levels of plasma NE and BRS-PRSA. Pearson coefficient r = − 0.70, p < 0.05.
