MRI volumetry of multiple sclerosis patients at baseline and changes over follow-up.
Without CDP group (n = 67) | With CDP group (n = 85) | HC group (n = 31) | Without CDP vs. CDP p-value | MS patients vs. HC p-value | |

T2 lesion volume absolute change, mean (SD) | 2.9 (5.5) | 4.2 (7.5) | – | 0.273 | – |
Percent brain volume change, mean (SD) | − 5.3 (3.0) | − 7.5 (3.8) | – | < 0.0001 | – |
Percent gray matter volume change, mean (SD) | − 5.8 (2.8) | − 7.1 (3.7) | – | 0.007 | – |
Legend: CDP – confirmed disability progression.
Baseline p-values were calculated using Student's t test while changes over follow-up were derived using analysis of covariance, correcting for age and sex. Volumes are presented in mL.
