Diagnostic Performance of Cerebroplacental Ratio Thresholds at Term for Prediction of Low Birthweight and Adverse Intrapartum and Neonatal Outcomes in a Term, Low-Risk Population.

Objectives: To investigate the screening performance and best threshold centile (5th vs. 10th) of the cerebroplacental ratio (CPR) in low-risk, term pregnancies to predict low birthweight and adverse intrapartum and neonatal outcomes in a term, low-risk population.

Methods: This was a blinded, prospective, cross-sectional study of low-risk singleton pregnancies at term.
