Table 3. 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).
| Anxiety rating scale | Cluster size (voxels) | Peak coordinates (mm) | Anatomical locations | p a |
| BAI | 81 | 20, −8, 46 | Anterior corona radiata, right (frontal lobe WM) | 0.019 |
| 62 | −18, −11, 49 | Anterior corona radiata, left (frontal lobe WM) | 0.018 | |
| PDSS | NS |
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.
