Abstract

Objective To investigate the prevalence of and twin pair concordance for endometriosis.Design A questionnaire survey incorporating validation.Setting An Australia-wide volunteer sample of female monozygotic (MZ) and dizygotic (DZ) twin pairs from the Australian National Health and Medical Research Council Twin Register.Patient(s) Twins were selected only on the basis of previous participation in twin research.Intervention(s) Questionnaires were sent to 3,298 individuals. Information was requested from physicians named by consenting twins.Main outcome measure(s) Reported endometriosis, validated where possible by pathology or surgical report.Result(s) Three thousand ninety-six (94%) of the twins and 145 (82%) of the physicians responded to the survey. Two hundred fifteen twins reported endometriosis, for a prevalence rate of .07 among question respondents. Tetrachoric twin pair correlations for self-reported endometriosis (MZ: n = 854 and DZ: n = 493) were rMz = .46+/-.09 and rDz = .28 +/-.13. When available medical and pathology reports were included, they changed to rMz =.52 +/-.08 and rDZ = .19+/-.16, suggesting that 51% of the variance of the latent liability to endometriosis may be attributable to additive genetic influences.Conclusion(s) These findings support the hypothesis that genes influence liability to endometriosis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Studies in Australian twins, the Icelandic population, and rhesus macaques provide strong evidence for a genetic contribution to endometriosis, with heritability estimated to be around 50%.

    “However, studies in Australian twins, 45 in the Icelandic population, 43 and in rhesus macaques 49 provide strong evidence for a genetic contribution to the disease with the heritability of endometriosis estimated to be around 50%. 45”
  • In twin sisters, prevalence of endometriosis and age of onset are similar.

    “In twin sisters a prevalence of endometriosis (158-161) and age of onset (162) are similar.”

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.
