Optic radiation and primary visual cortical data in the extremely preterm/extremely low birthweight participants vs. controls.

CI = confidence interval; ELBW = extremely low birthweight; EP = extremely preterm; FA = fractional anisotropy; MD = mean diffusivity; MRI = magnetic resonance imaging; OR = optic radiation; SD = standard deviation; V1 = primary visual cortex; λll = axial diffusivity; λ⊥ = radial diffusivity. *Adjusted for corrected age at MRI and intracranial volume.
