↵a Results of univariate linear regression analysis with follow-up lesion volume (square-root-transformed) as a dependent variable. Positive β-values indicate an increase in follow-up lesion volume.
↵b Mean.
↵c Documented for 70 patients.
↵d Median (first-third quartile).
↵e As measured by DWI-MRI (b=1000) or NECT.
