|---|---|---|---|---|
| vCSF | Corpus callosum | CCV | Whole cervical cord | |
| EDSS | R = 0.23, p = 0.4 | R = − 0.50, p = 0.06 | R = − 0.47, p = 0.08 | R = − 0.53, p = 0.04 |

| PASAT | R = − 0.65, p = 0.009 | R = 0.11, p = 0.7 | R = 0.16, p = 0.6 | R = 0.33, p = 0.2 |
| 9HPT | R = − 0.67, p = 0.007 | R = 0.64, p = 0.01 | R = 0.11, p = 0.7 | R = 0.49, p = 0.06 |
| T25FW | R = 0.08, p = 0.8 | R = − 0.40, p = 0.1 | R = − 0.54, p = 0.04 | R = − 0.53, p = 0.04 |
Significant relationships (p < 0.05) indicated in bold, and trends (p = 0.06) in italics.
9HPT was measured as the average of the inverse of the time for the dominant hand and the inverse of the time for the non-dominant hand (thus 9HPT score decreases for longer times), and T25FW was measured as the average time over 2 attempts (thus T25FW score increases for longer times).
