  1. AMN = Adrenomyeloneuropathy, C5 / C6 = cervical root 5 and 6; CSA = cross sectional area, PNP = peripheral neuropathy; HS = homogeneity score
  2. UPSS = ultrasound pattern sum score; UPSA = part A of the UPSS, UPSB = part B of the UPSS, UPSC = part C of the UPSS
  3. *: p < 0.05, **: p < 0.01, ***:p < 0.001 when compared to the healthy controls and AMN without neuropathy
  4. Median values of cross-sectional area measurements are provided for different sections of peripheral nerves (from proximal to distal in mm2) and for cervical nerve roots (diameter in mm). Significant enlarged nerves are marked in bold
