Effect sizes for group differences in NDI (left) and ODI (right) between control and YOAD subjects (Cohen's ds, mean difference contrast of control minus YOAD) using the conventional mean (blue) and tissue-weighted mean (red), for each white matter ROI. Positive effect sizes correspond to lower means in YOAD subjects and negative effect sizes to higher means in YOAD subjects. Points above the bars indicate significant differences between the control and YOAD group as determined by two-tailed Welch's t-tests on the group means (p < 0.05 Bonferroni-corrected across ROIs). ROIs are ordered as in Fig. 3.
