Due to the retrospective nature of the study, informed consent was waived. The study was approved by the local Institutional Review Board committee (HYMC-0048-22). All twin pregnancies delivered between September 2011 and August 2021, in which sonographic fetal biometry estimation was performed within 14 days before deliveries, were analyzed. This was a retrospective cohort analysis of women carrying twin gestations who delivered in a single, tertiary, university-affiliated medical center. We found that sEFW overestimated the birth weight for the second twin, with almost no other difference in accuracy measures or SGA prediction.

For SGA prediction, overall, there was a low sensitivity and a high specificity for all fetuses, with almost no difference between the first and second twins. Reliability analysis demonstrated an excellent correlation between the sEFW and the birth weight for both twins however, the Euclidean distance was slightly higher for the first twin (12.21%). No difference was found in median absolute systematic error ( p = 0.450), random error, or sEFW evaluations that were within 10% of the birth weight between the fetuses (65.3% vs. There was no statistically significant difference in the sEFW between the first and the second twins, but the second twin had a statistically significant lower birth weight (2434 vs. A total of 190 twin gestations were evaluated for the study. We conducted a retrospective analysis of the sonographically estimated fetal weight (sEFW) of all twin gestations performed within 14 days of delivery in a single center that aimed to evaluate the accuracy of sEFW in predicting neonatal weight and small for gestational age (SGA) by comparing the first fetus to the second. Accurate sonographic estimation of fetal weight is essential for every pregnancy, especially in twin gestation.
