Note: Multiple linear regression of GA and volume, FA and ADC, accounting for sex, magnitude of motion and laterality (for association and projection tracts). p‐Values are displayed.

Abbreviations: ADC, apparent diffusion coefficient; CST, corticospinal tract; FA, fractional anisotropy; GA, gestational age; IFOF, inferior fronto‐occipital fasciculus, ILF, inferior longitudinal fasciculus; UF, uncinate fasciculus.
