Introduction Our unit found, using the GROW customised analysis programme, that rates of SGA were far higher than expected: 40% detection antenatally and 11% SGA rates at birth. This study sampled the nearest cohort to SGA born babies (10th to 25th centile) to ascertain the false prediction of SGA rate comparing the GROW customised centile chart and then Intergrowth-2121st (I21) in our largely homogenous Caucasian population. Gardosi et al have shown that the GROW customised analysis has superior detection rates of SGA, thus identifying fetuses with an increased still birth risk1. Nicolaides has validated that hadlock EFW is most accurate when using I212.We wanted to compare the false allocation rates of both systems by looking at the nearest to normal cohort.
