Epidemiology of endometriosis in infertile women
Open accessAbstract
Objective To assess the epidemiological factors linked to endometriosis in infertile women.Setting Academic tertiary hospital.Design Case-control study.Patients One hundred seventy-four infertile women with endometriosis and 174 infertile women without endometriosis, all of them studied by laparoscopy.Results Women with endometriosis and infertility had a higher frequency of cycles < or = 27 days (26.4% versus 16.7%). A trend to a protective effect of smoking was detected. Social class, reproductive history, infertility history, previous abortions, age, family history, age at menarche, and duration of menstrual flow were similar in both groups.Conclusion Cycles < or = 27 days was the only risk factor that seemed to be associated to endometriosis in infertile patients. However, predictive values were low. A trend to a protective effect of smoking was detected.

“epidemiological studies analyzing the cycle of women with endometriosis have shown that the early first cycle (before the age of 11) is associated with the risk of endometriosis [43,44,45,46]”

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.
