Mathematical models for fetal growth: application for biparietal diameter measurement.
Evaluation of the adequacy of fetal growth by measurements of fetal size required theoretical formulae for the assessment of present size from previous measurements. The various models presented in the literature assume the same mathematical formula for the whole pregnancy. In this study, a model of different polynomial approximations for the early and late stages of the pregnancy is compared to two models which assume a single formula for both stages of the pregnancy. The standard error of estimate is lower for the sectioned model.
