| MNI coordinates | ||||||
|---|---|---|---|---|---|---|
| Brain region | Side | x | y | z | Number of voxels | Z score |
| BT > CG | ||||||
| Hypothalamusa | R/L | −8 | −2 | −12 | 5 | 2.01 |

Abbreviations: BT, buprenorphine treatment for opioid use disorder; CG, comparison group; PAG, periaqueductal gray; rs-FC, resting-state functional connectivity.
Except this a priori region of interest, all regions listed above were cluster-level whole-brain corrected (family-wise error correction < .05) at voxel-wise P = .001.
