GROWTH OF THE FETAL BIPARIETAL DIAMETER DURING NORMAL PREGNANCY
Abstract
Summary: The fetal biparietal diameter was measured by ultrasound during normal pregnancy. The range of biparietal diameter values for each week of pregnancy from 13 weeks until term (1029 measurements) was determined and longitudinal data (646 measurements) were used to illustrate the variation in growth rate according to fetal maturity, head size and weight.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
