Average values for bundle volume, Cl, bundle length, and average MD for the groups with CC scores 1 (normal CC), 2 (mild thinning of the CC), and 3 (severe thinning of the CC). Red triangles indicate the CC; blue squares, the PLIC L; and green open circles, the PLIC R. In total, 72 CC fiber bundles were evaluated, with n = 19 in group 1, n = 40 in group 2, and n = 11 in group 3 for the CC. Displayed is the mean, and the error bar displays the standard average of the mean. Asterisk denotes a significant difference (P < .05).
