Fig. 4.

Intraindividual (dots) and mean (black lines) change (Δ) of the UPSS, the MRCSS, the INCAT overall disability score, and the NCSS for all 3 classes. There is significant higher number of patients with improvement (black dots) in class 1 for MRCSS compared to class 2 (single asterisk) and for INCAT compared to classes 2 and 3 (double asterisk), although intraindividual course can be distinct, independently from morphological pattern. Patients with unchanged or deteriorated scores compared to baseline are marked with white dots. INCAT = inflammatory neuropathy cause and treatment disability score, MRCSS = medical research council sum score, NCSS = nerve conduction studies score, UPSS = ultrasound pattern sum score
