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

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

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