NICU: Neonatal intensive care unit, CNS: central nervous system. The infant with cardiovascular malformation was excluded from the analysis of symptoms
^aNeonatal outcomes were divided into CNS symptoms (jitteriness, agitation, lethargy), jaundice, respiratory symptoms (apnea, need for CPAP and/or ventilation), renal symptoms (increased plasma creatinine levels) and thyroid symptoms (increased levels of thyroxine)
