^aSGA was defined as gestational age-adjusted birth weight < 10th percentile of the customized chart. AGA is defined as gestational age-adjusted birth weight > 10th and < 90th percentile according to the customized chart. LGA was defined as gestational age-adjusted birth weight > 90th percentile of the customized chart
