Mean±SD are shown, otherwise indicated. Chi-square was used to test difference in gender, whereas unpaired t-test was used to test all other measures. F = female, M = male, mL = millilitre, mm = millimetres, s = second, EDSS = expanded disability status scale, DMT = disease modifying therapy, T2LV = T2 lesion volume, GM = grey matter, WM = white matter, CSF = cerebrospinal fluid, ICV = intracranial volume, BPF = brain parenchymal fraction, FA = fractional anisotropy, MD = mean diffusivity, AD = axial diffusivity, RD = radial diffusivity, NS = not significant, NA = not applicable.
