Estimated fetal weight was calculated using the Hadlock formula. The primary growth abnormalities investigated were late-onset selective fetal growth restriction (late-onset sFGR), birth weight discordance (BWD)\u00a0\u226520\u202f%, and small for gestational age (SGA). Binary logistic regression analysis was used to develop prediction models for growth abnormalities using EFWD alone and in combination with other clinical predictors.
