  • These analyses include only those children without a severe gross motor impairment (GMFCS score < 1). Antenatal epoch includes the following variables: gestational age of 23–24 weeks; gestational age of 25–26 weeks; single mother; complete course of antenatal steroids; cesarean delivery; and delivery for preeclampsia or fetal indications. Neonatal epoch includes the following variables: SNAP-II in the top quartile; MV or high-frequency ventilation at 7 days; late bacteremia; pneumothorax; PIE; Pao2 in the lowest quartile (week 1); Pao2 missing (week 1); transfusions (packed red blood cells); PD; EPPD; ventriculomegaly; echolucent lesion; echodense lesion; NEC stage II or worse; methylxanthine; PDA; and PDA ligation. Thirty-six weeks' PMA epoch includes the following variables: CLD without MV (CMV or high-frequency ventilation) at 36 weeks and CLD with MV.
