AI Article Synopsis
- The study aimed to compare various fetal weight formulas and biometric tables to find the most accurate method for estimating the weight of Brazilian newborns.
- Methods used included the evaluation of several commonly used formulas (e.g., Stirnemann, Shepard) with different biometric tables (e.g., Snijders and Nicolaides, Papageorghiou), and the Pedreira database was used as a benchmark.
- Results indicated that the best correlation for estimating newborn weight was achieved using Snijders and Nicolaides' biometric table combined with Stirnemann's weight formula, while Shepard's formula showed the lowest average relative error when paired with multiple biometric tables.
Article Abstract
To compare the best fetal weight formula with different biometric tables on the weight of Brazilian newborns. This observational study has tested the performance of different common fetal weight formulas and biometric tables. Weight estimates were performed by the methods of Warsof . (1977), Shepard . (1982), Hadlock . (1985), Furlan . (2012) and Stirnemann . (2017). The biometric tables selected were the following: Snijders and Nicolaides (1994), Hadlock . (1984), Papageorghiou . (2014) and Kiserud . (2016) and correlated to Pedreira . (2011) database, which was considered the gold standard. Statistical analyses were performed using the mean relative error, average absolute error and the Pearson correlation coefficient (r). The best r was found when using the Snijders and Nicolaides (1994) biometric table with weight formula by Stirnemann . (2017). The average relative error was lower when using weight formula by Shepard . (1982) with biometric tables by Snijders and Nicolaides (1994), Papageorghiou . (2014) or Kiserud . (2016). On average, absolute error, the lowest r was obtained for the Furlan . (2012) weight formula and the Papageorghiou . (2014) biometric table. The best correlation was found for biometric table by Snijders and Nicolaides (1994) and fetal weight formula calculation for the estimation of Brazilian newborn weight by Stirnemann . (2017).
