  1. Weight Z score is according to Fenton growth charts. PH refers to levels in the umbilical cord. Birth weight is in grams corrected for gestational age. Resuscitation refers to neonatal resuscitation in the delivery room. aRefers to mode of delivery (vaginal and cesarean together). bRefers to SGA, AGA and LGA together. AGA appropriate for gestational age, LGA large for gestational age, SD standard deviation, SGA small for gestational age
