Cross-sectional reference values of cerebral ventricle for Chinese neonates born at 25-41weeks of gestation.

Abstract

We recommend using the GA-based AHW reference values and birth weight-based TOD and VI ones. We also present a comparison of GA-based upper limits from all available reference intervals. Moreover, we determine that measurement errors are the primary cause of influential points and heteroscedasticity in TOD and VI studies and infer that the studies of TOD and VI are vulnerable to them. •Reference values of infantile cerebral ventricles are vital in diagnosing and treating cerebral ventricular dilatation. •Precursors established gestational age-based reference values subjectively. •We set cross-sectional reference values based on the most correlated variables for Chinese neonates and compared all available gestational age-based upper limits. •Influential points and heteroscedasticity mainly caused by measurement errors are common in TOD and VI studies.
