Contextual performance of diagnostics for fetal surveillance.

Abstract

Identification of women and fetuses at high risk for adverse perinatal outcomes is a central preoccupation in prenatal care. In recent years, the sonographically derived cerebroplacental ratio (CPR) has gained popularity for its ability to identify compromised fetuses among pregnancies with suspected growth restriction or placental disease. Although numerous studies and systematic reviews have examined the predictive performance of the CPR, there were many limitations.
