Fractional arm volume (AVol) and fractional thigh volume (TVol) soft tissue parameters were measured with a commercially available automated software utility (5D Limb Vol; Samsung Medison Co, Ltd, Seoul, Korea). Three conventional weight prediction models that included only 2D size parameters were compared to FLV models that included AVol or TVol. Estimated and actual birth weight (BW) were assessed for the mean percent difference\u2009\u00b1\u2009standard deviation of the percent differences. Systematic errors were evaluated by the Student <jats:italic>t<\/jats:italic> test, and random errors were compared by the Pitman test for correlated variances. The proportion of neonates with estimated fetal weight within 10% of BW was compared between groups by the McNemar test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Ninety gravid women were enrolled with pregestational (26.7%) or gestational (73.3%) diabetes.

Random errors for the AVol (6.2%) and TVol (6.9%) models were significantly more precise than the other 3 prediction models: Hadlock et al (7.8%; <jats:italic>Am J Obstet Gynecol<\/jats:italic> 1985; 151:333\u2013337), INTERGROWTH\u201021st (8.0%; <jats:italic>Ultrasound Obstet Gynecol<\/jats:italic> 2017; 49:478\u2013486), and Schild et al (8.6%; <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.01).
