Endometriosis in monozygotic twins
Open accessAbstract
Objective To describe the occurrence of endometriosis in monozygotic twins.Design Postal questionnaire plus confirmation of disease status.Setting Twins were recruited via the American Endometriosis Association and the National Endometriosis Society of Great Britain and via British gynecologists.Result(s) Fourteen twin pairs were concordant for endometriosis, and two were discordant. Nine pairs of twins had moderate-severe endometriosis.Conclusion(s) These findings contribute to the growing body of literature that suggests endometriosis has a genetic basis.

Since the 1940s, a much higher incidence of endometriosis has been described among women from families in which women suffered from endometriosis, and among siblings, especially monozygotic twins, where co-occurrence exceeds 80%.
“Since the 1940s, a much higher incidence among women from families in which women suffered from endometriosis has been described, as well as a high incidence among siblings, especially monozygotic twins, where the percentage of co-occurrence exceeds 80% [177].”

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.
