Abstract
Objective. To establish an umbilical cord thickness nomogram from anatomy ultrasound scans performed between 18 and 23 weeks of gestational age in singleton pregnancies, and compare it to two previously published nomograms.
Material and methods. In this retrospective cohort study of 1107 patients, a total of 650 singleton pregnancies were included. The umbilical cord diameter measurements were performed at the level of fetal abdominal wall insertion, and were correlated with gestational age (GA) and estimated fetal weight (EFW). Statistical analysis with non-parametric polynomial least squares regression analysis was performed.
Results. A statistically significant correlation ...
