Implication
Population study demonstrates aligned birth weight and estimated fetal weight medians across gestational age, indicating improved detection of preterm growth restriction.
Key Points
- To construct fetal and neonatal weight charts that include both delivered and in utero infants across gestational ages to prevent the underestimation of growth restriction in preterm infants.
- Modeled birth weight (BW) and estimated fetal weight (EFW) standards across gestational age cohorts, incorporating fetuses remaining in utero.
- Birth weight and estimated fetal weight trajectories demonstrate a shared common median throughout gestation.
- The spread of values around the common median differs between birth weight and estimated fetal weight distributions.
