Figure 4.

Differences in MR metrics in the optic radiations between lesions and NAWM. AVF, MVF, and g-ratio are reported as median values with interquartile range and minimum and maximum for both NAWM and lesions. Open circles in the AVF and MVF plots denote outliers. Differences between NAWM and lesions surviving Bonferroni correction are marked with an asterisk (*); others are denoted as ns.

NAWM: normal-appearing white matter; AVF: axonal volume fraction; MVF: myelin volume fractions; ns: not significant.
