Sonographic EFW and macrosomia: Is there an optimum formula to predict diabetic fetal macrosomia?

Abstract

All 31 formulas for EFW had comparably poor accuracy for prediction of macrosomia. Delivery decisions based on EFW will often be in error. Future studies should determine whether specific sonographic measurements, ratios, or differences are better than EFW or birthweight as predictors of birth trauma.
