Brain T2 and T1 lesion volumes and number and length of cervical cord lesions from the whole patient sample and the three multiple sclerosis (MS) phenotypes
| All patients | RRMS | SPMS | PPMS | p Value | |
| Brain T2 LV (ml) | 15.3 (15.5) | 11.4 (9.1) | 22.2 (20.8) | 8.0 (5.9) | 0.08 |
| Brain T1 LV (ml) | 5.3 (5.1) | 3.4 (3.3) | 6.4 (3.9) | 0.9 (0.7) | 0.03 |
| Number of cord lesions | 2.0 (1.4) | 1.6 (1.3) | 2.8 (1.3) | 1.5 (1.0) | 0.002 |
| Length of cord lesions | 3.3 (2.5) | 2.5 (1.0) | 4.7 (2.8) | 2.5 (1.9) | 0.004 |
Values are expressed as means (SD). LV=Lesion volume; RRMS=relapsing-remitting MS; SPMS=secondary progressive MS; PPMS=primary progressive MS. For statistical analysis, see text.
