Differences in DTI metrics between VLBW and control adults.

Results of the tract-based spatial statistics (TBSS) analysis demonstrate significant differences between groups in A) fractional anisotropy (FA), B) axial diffusivity and C) radial diffusivity. Lower values of diffusion metrics in VLBW relative to controls are displayed in blue, while higher values are shown in red-yellow. Lighter colours reflect smaller p-values. Results are overlaid on the mean FA image (TFCE-corrected for multiple comparisons p < 0.05). Specific regions exhibiting differences in DTI metrics are listed in Supplementary Table S4. Slices displayed: z = 27, 17, 7, −3, −13; neurological convention (left of the image is left of the brain).
