Percentages represent frequency of infants per total screened infants in each risk category (row percentages)

No infants with low birth weight and GA over 41 weeks were identified among diabetic mothers; BG – blood glucose, BW – birth weight, GA – gestational age, NICU – neonatal intensive care unit
