Italic data are statistically significant
aSGA = small for gestational age; bAdverse outcomes = neonatal resuscitation, respiratory distress syndrome, disseminated intravascular coagulation, intra-ventricular hemorrhage, leucomalacia, sepsis, necrotic enteritis, retinopathy of prematurity; cFisher’s exact test with Holm-Bonferroni correction, for all comparison; ns, not significant
