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.
