Arterioles, mm/s; mean (SD) 3.95 (0.59) 4.08 (0.60) 3.51 (0.81) 3.48 (0.88) 3.59 (0.69) 0.1a 0.01 b 0.009 b 0.046 b 0.42b
Venules, mm/s; mean (SD) 3.11 (0.46) 3.23 (0.52) 2.76 (0.50) 2.75 (0.53) 2.80 (0.45) 0.064a 0.003 b 0.005 b 0.048 b 0.48b
  1. HC = healthy control; OD = right; OS = left; MS = multiple sclerosis; MSNON = multiple sclerosis without optic neuritis; MSON = multiple sclerosis with optic neuritis; SD = standard deviation
  2. aPaired t-test
  3. bMixed-effects linear regression adjusted for age, sex, and within-subject inter-eye correlations in HCs (as well as disease duration between the MS groups)
  4. P ≤ 0.05 indicates significance
