  • a P < .01, result of the test comparing the severity of cerebral palsy according to ultrasound abnormalities (none, isolated IVH, or white matter abnormalities, ie, persistent echodensities, ventricular dilation, cystic PVL, and IPH grouped).

  • b Severity of cerebral palsy was classified as follows: walk, able to walk independently; sit, unable to walk but able to sit independently; cannot sit, unable to maintain head and trunk control.

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

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