Maternal age-specific rates of numerical chromosome abnormalities with special reference to trisomy

Hassold, T., Chiu, D.·1985·Human Genetics

Abstract

The effect of maternal age on the incidence of chromosomally normal spontaneous abortion and different categories of chromosome abnormality among all clinically recognized human pregnancies was evaluated. The results provide no evidence for a significant association of age with sex chromosome monosomy or polyploidy, but clearly demonstrate an effect of age on the frequency of trisomy and chromosomally normal spontaneous abortions. Estimated maternal age-specific rates of trisomy among all recognized pregnancies were calculated and suggest that a majority of oocytes of women aged 40 years and older may be aneuploid.

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.
