a Participants were divided into the rehabilitation group and the control group. All participants were assessed with ICA, serum NfL and their EDSS score at the baseline and after 8 weeks. b ICA had a significant correlation of r = − 0.79 (p < 10− 10) with NfL at baseline (also reported in Fig. 5a), and a significant correlation of r = − 0.75 (p < 10− 8) after the 8 weeks. c The bars indicate the average ICA, EDSS and the level of NfL at the baseline, and after the 8 weeks separately for each group of participants. Connected lines from the light gray bars (baseline) to dark gray bars (follow-up) show the changes in score for each individual. The difference between the two bars are reported in Cohens’ d below each pair of the bar graphs. The icons used in this figure are taken from Microsoft Office free icon library
