  1. Data are presented as medians with interquartile ranges (IQR 25–75%). RDN = Renal denervation, GM = geometric mean images, with muscle as background, SPECT = single photon emission computed tomography. n.a. = not available, *data from n = 20 patients since in one patient a 123I–vial was not included during the scintigraphy and therefore the percentage of injected dose 123I–mIBG could not be calculated
