Demographic characteristics of subjects in the cross-sectional cohort.

Category	Number of subjects	Age (SD)	Sex ratio (female : male)	Disease duration (SD)
Healthy controls	22	33.5 (9.1)	13 : 9	N.A
RRMS	52	41.8 (11.6)	37 : 15	10.3 (7.3)
SPMS	9	59.5 (6.1)	8 : 1	27.6 (10.6)
PPMS	7	56.2 (6.4)	4 : 3	19.7 (12.9)

RRMS: relapsing-remitting multiple sclerosis; SPMS: secondary progressive multiple sclerosis; PPMS: primary progressive multiple sclerosis; SD: standard deviation.
