Abbreviations: RRMS, relapsing‐remitting multiple sclerosis; SPMS, secondary‐progressive multiple sclerosis; PPMS, primary‐progressive multiple sclerosis; EDSS, Expanded Disability Status Scale; NBV, normalized brain volume; NGMV, normalized gray matter volume; NWMV, normalized white matter volume; NLV, normalized lesion volume; NAWM, normal‐appearing white matter, FA, fractional anisotropy; MD, mean diffusitivity; AD, axial diffusitivity; RD, radial diffusitivity.
Values listed are mean ± SD for normally distributed variables, P values were Bonferroni‐corrected where applicable.
Variables were not normally distributed and therefore median (interquartile range) is provided.
Values listed are volumes normalized for head size; left and right were averaged.
