The Development of an Alternative Growth Chart for Estimated Fetal Weight in the Absence of Ultrasound: Application in Indonesia

“…The existing models were developed based on data recorded within one week of delivery and within 14 days of the last ultrasound scan, while the proposed model: EFW (g) = 109.16FH -272 [Eq.1] was developed based on FH measurement recorded between 35 and 41 weeks (before delivery) and actual birth weight. 1,2,3,4 The results show that the proposed model is significantly more capable (less error) than the existing models in predicting fetal weight during pregnancy, even at earlier GAs. It also can be seen that the prediction errors are less pronounced when the pregnancy reaches advanced GAs.…”

“…In this research, the proposed clinical quadratic EFW-GA model: EFW = 137.173GA -1:035 GA2 -675:199 [Eq.2] was used to develop the chart. 1 This model was compared with the existing model through several analysis.…”
