Associations between birthweight and DTI metrics in VLBW adults.

Results of permutation tests of correlation in FSL demonstrate correlations between birthweight and A) fractional anisotropy (FA), B) axial diffusivity, and C) radial diffusivity, within principle white matter tracts. Areas of positive correlation are depicted in red-yellow, while negative correlations are represented in blue. Lighter colours reflect smaller p-values. Results are overlaid on the mean FA image (TCFE-corrected for multiple comparisons p < 0.05). Specific regions exhibiting correlations between birthweight and DTI metrics and are listed in Supplementary Table S8. Slices displayed: z = 27, 17, 7, −3, −13; neurological convention (left of the image is left of the brain).
