Morphological parameters of Parkinson patients and healthy controls

		Parkinson's disease median (IQR) n = 15	Controls median (IQR) n = 10
Phosphorylated alpha‐synuclein deposits		n = 7	n = 0
IENFD PGP 9.5 proximal leg [fibers/mm]		6.36 (5.28–9.76)	7.54 (6.55–9.97)
Sweat glands PGP 9.5 [%]		10.40 (6.99–15.27)	9.30 (7.57–11.55)
Erector pili PGP 9.5 [fibers/µm]		0.04 (0.03–0.04)	0.04 (0.02–0.04)
Erector pili TH [fibers/µm]		0.04 (0.03–0.05)	0.03 (0.02–0.04)
Arterial vessel PGP 9.5 [%]		5.20 (4.70–15.37)	7.90 (4.90–11.55)
Arterial vessel TH [%]		7.25 (5.23–11.15)	5.70 (4.15–14.18)

Table shows the morphological parameters of proximal leg skin biopsies in Parkinson patients and healthy controls. No structural differences between the patient and the control group could be found (ns). IENFD, intraepidermal nerve fiber density; TH, tyrosine hydroxylase. %: percent surface area of the sweat glands and vessels covered with immunoreactive nerve fibers.
