Regions showing a significant positive correlation between the anxiety rating scale scores and fractional anisotropy (FA) in WM regions showing a significant between-group differences in patients with panic disorder (PD).

Note: There was no region of significant negative correlation between BAI scores and FA in patients with PD. Regions remained significantly after multiple comparison correction (2 measurements; Bonferroni correction, level of significance alpha = 0.05/2 = 0.025) are shown. BAI, Beck Anxiety Inventory; NS, non-significant. aFamily-wise error corrected p value using the Threshold-Free Cluster Enhancement method.
