A systematic
literature search was performed using MEDLINE/PubMed, Embase, Scopus, and Web
of Science for studies published from database inception to June 2023. We
queried quantitative studies of pregnant women at term (≥ 37 weeks’ gestation)
with a growth ultrasound performed between 34 and 37 weeks. Multiple gestations
and fetuses with anomalies were excluded. Studies were eligible for inclusion
if the EFW was compared to the actual birth weight. Search terms included
“gestation-adjusted projection”, “fetal weight”, “fetal weight extrapolation”,
“ultrasound”, and “birth weight”. The quality of studies was evaluated
utilizing the Newcastle-Ottawa Scale, and the risk of bias was assessed using
the ROBINS-I tool.
