* p < 0.01.
PF = parenchymal fraction: whole brain parenchyma/intracranial volume; VF = ventricular fraction: ventricle volume/whole brain volume; EDSS = Expanded Disability Status Scale; MSFC = MS Functional Composite; TWT = Timed Walk Test; 9-HPT = nine hole peg test; PASAT = paced auditory serial addition test 3 seconds.
