We aimed to investigate, among women delivering neonates weighing greater than 3500 g, whether having had a sonographically estimated fetal weight in temporal proximity to delivery was associated with the risk of cesarean delivery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We conducted a retrospective cohort study of term nulliparous women delivering live\u2010born, cephalic, singleton, nonanomalous fetuses with birth weights of greater than 3500 g.
