Title: Distribution of growth assessments across gestation in
the lower-risk nested cohort used to derive the sex-specific growth
curves.
Caption: Panel A: Scatter plot of EFWs and birth weights used to derived
the new sex-specific standard. Colors denote the study visit at which
the weight was measured. Panel B: Fitted nuMoM2b male and female fetal
growth curves alongside the Hadlock sex-neutral growth curve. For ease
of interpretation, the x axis (gestational age) in panels A and B are
alginged, and the y axis (weight) scales are equivalent. Panel C:
Sex-specific formulas for expected fetal weight at a given gestational
age, where GA is in weeks, decimal format. EFW, estimated fetal weight;
GA, gestational age.
