Purpose: To develop and to evaluate a specific sonographic weight formula for fetuses with extreme macrosomia (≥4500 g). Material and methods: A statistical estimation technique known as “gradient boosting with component-wise P-splines” was applied to a group of 174 fetuses with a birth weight (BW) ≥4500 g. Each fetus underwent an ultrasound examination with complete biometric parameters within 7 days of delivery. Exclusion criteria were multiple pregnancy, intrauterine death, and major structural or chromosomal anomalies. A new formula was derived using the data obtained and was then compared with currently ava…
