  • a Nonsignificant, result of the test comparing the distribution of cerebral palsy subtypes according to ultrasound abnormalities (none, isolated IVH, or white matter abnormalities, ie, persistent echodensities, ventricular dilation, cystic PVL, and IPH grouped).

  • b Isolated IVH was isolated grade I, II, or III IVH.

  • c White matter abnormalities included persistent echodensities, ventricular dilation, cystic PVL, and IPH.
