Neonatal adverse outcome in twin pregnancies complicated by small-for-gestational age: twin vs singleton reference chart.

The singleton charts classified one third of twins as SGA, both prenatally and postnatally. SGA infants according to the twin specific charts, but not the singleton charts, had a significantly increased risk of adverse neonatal outcomes. This study provides further evidence that twin specific charts are better predictors of adverse neonatal outcomes; the use of these charts may reduce misclassification of twins as SGA and improve identification of those infants who are truly growth restricted.
