Why was this study conducted
Fetal growth restriction (FGR) is the leading cause of intrauterine fetal death, neonatal death, and short-term and long-term complications worldwide. It is difficult to evaluate the potential growth of a fetus. Therefore, different countries and associations have developed different guidelines to screen for fetuses with suspected FGR. The purpose of this study was to investigate the predictive effect of three different diagnostic criteria of FGR on small-for-gestational-age (SGA) and adverse neonatal outcome (ANO), so as to find a better FGR-definition for Chinese population.
