Fig. 5.

The relationship between GA at birth and fibre cross-section (FC), corrected for PMA at scan. Fixels with a significant positive correlation (corrected p < 0.05) are shown on the top row, and streamlines passing through significant fixels (coloured by direction red: left-right; green: anterior-posterior; blue: inferior-superior) are shown on the bottom row, in the axial plane. The scatter plot shows the partial correlation between GA and FC averaged over all significant fixels, corrected for PMA. The single slice axial plane in the FC panel shows a close up of fixels within the cerebellum that are significantly correlated with GA (red-yellow) overlaid on the fixel template (black), highlighting which fibres within crossing fibre regions are significantly associated with prematurity.
