Summary of Between-Group FSL Tract-Based Spatial Statistics Analyses Results
| Contrast | Whole-Group Analysis |

|---|---|---|---|---|
| FA | AD | RD | MD | |
| Del > NoCNV | + | − | − | − |
| NoCNV > Del | − | − | − | − |

Significant voxelwise comparisons (p < .05) are indicated by a plus sign (+) (less significant) or two plus signs (++) (more significant), and nonsignificant results (p > .05) are indicated by a minus sign (−). All the p values were corrected using the threshold-free cluster enhancement algorithm in FSL Tract-Based Spatial Statistics.
AD, axial diffusivity; Del, deletion; Dup, duplication; FA, fractional anisotropy; MD, mean diffusivity; NoCNV, no large copy number variants; RD, radial diffusivity.
