Mean and standard deviation of MRI measures for each subject group.

RR-MS = relapsing-remitting MS; PP-MS = primary-progressive MS; All patients = both patients groups together (RR-MS & PP-MS); T2LV = T2-weighted lesion volume; T1LV = T1-weighted lesion volume; NBV = normalized brain volume; NGMV = normalized gray matter volume; NWMV = normalized white matter volume; Temporal MA = temporal lobe -medial aspect; Temporal LA = Temporal lobe—lateral aspect. Normalized volumes are in mL, cortical thickness is in mm, subcortical volume is in mm3.* p ** p *** p # p Mean and standard deviation of MRI measures for each subject group.
