Mean (SE); All MD, AD, and RD values should be multiplied by 10⁻³

^Ψ

P value determined using Wilcoxon rank sum test.

^§

dMRI data not available for one baby from No CP group due to localized motion artifacts.

Abbreviations: STR – superior thalamic radiations; FA – fractional anisotropy; MD – mean diffusivity; AD – axial diffusivity; RD – radial diffusivity; L – left; R – right; B – bilateral
