was determined using the Hadlock (BPD-HC-AC-FL) formula. The accuracy of prediction of fetal macrosomia was assessed using the area under the receiver-operating characteristics curve (AUC). Results: The prevalence of fetal macrosomia (birthweight ≥ 4000g) was 13% (n=33). The EFW percentile had the best predictive performance for fetal macrosomia (AUC 0.875, 95% CI 0.795-0.955), with a negative predictive value of 96.7% and a positive predictive value of 36.5%. The predictive performance of EFW percentile was higher in the subgroup of women requiring insulin and/or oral antidiabetic drugs (AUC 0.955, 95% CI 0.858-1.000; PPV 77.8%, NPV 96.3%). Conclusions: Ultrasound biometry in the late third trimester is effective in identifying those fetuses that are unlikely to become macrosomic by the time of birth. Among the patients treated pharmacologically, the examination is useful for prediction of fetal macrosomia. Supported by AZV 15-27630A.
