Results of logistic regression with all clinical and MRI parameters, with the presence/absence of clinical disease progression after 5.5 years as the dependent variable
| Predictor | B | OR | 95% CI | p Value |
| Intercept | −0.97 | |||
| Disease type (PO vs RO) | 2.50 | 12.22 | 1.39 to 107.31 | 0.024 |
| aPVVC 0–2 | 0.16 | 1.17 | 1.01 to 1.35 | 0.035 |
Dependent variable was presence or absence of progression after 5.5 years, defined as an increase in EDSS of at least 1 point.
aPVVC 0–2, annualised percentage ventricular volume change within the first 2 years; B, parameter estimates (b coefficients); EDSS, Expanded Disability Status Scale; intercept, log odds (logit estimate); PO, progressive onset; RO, relapsing onset.
