Pearson's correlation coefficients between PHQ‐9 scores and DTI metrics in white matter tracts where differences were found between groups
| WM Tract | skeleton – FA | skeleton – FA‐FW | VBA – FA | VBA – FA‐FW |

| IFOF L | R = −0.054 | R = 0.022 | R = −0.075 | R = −0.005 |
| ILF L | R = −0.065 | R = −0.008 | R = −0.100 | R = −0.051 |

a
p < .05 (Bonferroni corrected).
b
p < .01 (Bonferroni corrected).
Correlations were computed only within the MDD group. Bonferroni correction was used to correct the P values for multiple comparisons. Significant correlations were found for RD index inside the CST L and SLF L for the skeletonized analysis and inside the CST L for the VBA analysis. For RD‐FW only inside the CST L when the skeletonized approach was used. The names of the tracts are the same of Table 2.
