NFL in serum (a) and CSF (b) in healthy controls and patients at baseline. Lines show median and interquartile range. For S-NFL, patient group (n = 41) median was 17 pg/mL (interquartile range 12–22 pg/mL) and healthy control (HC) (n = 22) group median was 11 pg/mL (interquartile range 8–14 pg/mL). For CSF-NFL, patient group median was 895 pg/mL (interquartile range 300–2060 pg/mL) and HC group median was 212 pg/mL (interquartile range 151–289 pg/mL). P- values from Mann-Whitney U test
