World Endometriosis Research Foundation Endometriosis Phenome and biobanking harmonization project: II. Clinical and covariate phenotype data collection in endometriosis research
Open accessAbstract
OBJECTIVE: To harmonize the collection of nonsurgical clinical and epidemiologic data relevant to endometriosis research, allowing large-scale collaboration. DESIGN: An international collaboration involving 34 clinical/academic centers and three industry collaborators from 16 countries on five continents. SETTING: In 2013, two workshops followed by global consultation, bringing together 54 leaders in endometriosis research. PATIENTS: None. INTERVENTION(S): Development of a self-administered endometriosis patient questionnaire (EPQ), based on [1] systematic comparison of questionnaires from eight centers that collect data from endometriosis cases (and controls/comparison women) on a medium to large scale (publication on >100 cases); [2] literature evidence; and [3] several global consultation rounds. MAIN OUTCOME MEASURE(S): Standard recommended and minimum required questionnaires to capture detailed clinical and covariate data. RESULT(S): The standard recommended (EPHect EPQ-S) and minimum required (EPHect EPQ-M) questionnaires contain questions on pelvic pain, subfertility and menstrual/reproductive history, hormone/medication use, medical history, and personal information. CONCLUSION(S): The EPQ captures the basic set of patient characteristics and exposures considered by the WERF EPHect Working Group to be most critical for the advancement of endometriosis research, but is also relevant to other female conditions with similar risk factors and/or symptomatology. The instruments will be reviewed based on feedback from investigators, and-after a first review after 1 year-triannually through systematic follow-up surveys. Updated versions will be made available through http://endometriosisfoundation.org/ephect.

Written from the paper’s full text.
TL;DR
The WERF EPHect Working Group developed standard recommended (EPQ-S) and minimum required (EPQ-M) self-administered questionnaires to harmonize nonsurgical clinical and epidemiologic data collection in endometriosis research. The instruments cover pain, subfertility/reproductive history, menstrual and hormone history, medical/surgical history, medication use, and personal/lifestyle information, with planned periodic review.
Key findings
- The standard recommended (EPHect EPQ-S) and minimum required (EPHect EPQ-M) questionnaires contain questions on pelvic pain, subfertility and menstrual/reproductive history, hormone/medication use, medical history, and personal information.
- Development involved 34 clinical/academic centers and three industry collaborators (54 participants) from 16 countries on five continents, and was based on questionnaires from eight centers that had published on >100 cases.
- Pilot work in several EPHect centers showed the full standard questionnaire requires 25 to 40 minutes to complete in paper or electronic form; the EPQ-M excludes life-course sections considered secondary in some settings.
- Pain intensity is measured on an 11-point numerical rating scale; the EPQ includes the SF-MPQ, recommends SF-MPQ-2 as standard, and includes the 13-question Pain Catastrophizing Scale; menstrual flow is classified using a validated menstrual pictogram.
Methods
- International consensus process: two workshops in March 2013 and July 2013, followed by global consultation, bringing together 54 leaders in endometriosis research; 34 clinical/academic centers and three industry collaborators from 16 countries participated.
- Questionnaire development used systematic comparison of questionnaires from eight centers, a PubMed literature search, expert review of question phrasing and temporality, patient/volunteer piloting, face-validity review, and consensus at Workshop II.
- No patients were included; ethics committee or IRB approval was not required for formation of the Working Group, literature review, or consensus on best practices, and the endeavor did not include human subjects data.
Limitations
- Stated: the EPQ is not designed for clinical practice to inform immediate clinical decisions, nor for in-clinic completion and immediate review.
- Stated: the Working Group excluded potentially important exposures such as nevi and freckles, sun exposure, and in utero exposures, and did not include validated generic health status or depression/anxiety scales because some require registration and/or payment; self-administered questionnaires are also not appropriate for accurately collecting detailed infertility treatment data.
- Evident from the text: no formal psychometric validation of the full EPQ is reported; validation relies on previously validated component questions, piloting, and face-validity review.

![FIGURE 2 Mechanisms by which the nervous system can be engaged in endometriosis (17). Endometriotic lesions appear to be able to engage the nervous system throughout the neuroaxis. In addition to developing their own innervation [both peptidergic sensory (blue) and sympathetic nerve fibers (green)], all nerve fibers within the pelvis may become sensitized (red asterisk), as may the central nervous system. The extent of peripheral sensitization is dynamically modulated by estradiol and sympathetic-sensory coupling, and other factors may modulate central sensitization.](/paper-figures/32d34b995b604be19f89b01a4321aed4/world-endometriosis-research-foundation-endometriosis-phenome-and-biobanking-figure-2.jpg)

- Partly supportedcites [41] Piltonen, 2012, Oral, transdermal and vaginal combined contraceptives induce an increase in markers of chronic inflammation and impair insulin sensitivity in young healthy normal-weight women: a randomized study, Hum Reprod sourceExperimental — accuracy not yet measured
The Measurements section reports biomarker sampling at baseline and after 5 and 9 weeks of contraceptive treatment. The Serum levels of lipids, CRP and PTX-3 section reports changes in several markers over that period, supporting the point about recent hormone use. The study does not establish an effect of long-term use. (LLM, conf=0.87)
- Partly supportedcites [42] Rossouw, 2008, Inflammatory, lipid, thrombotic, and genetic markers of coronary heart disease risk in the women's health initiative trials of hormone therapy, Arch Intern Med sourceExperimental — accuracy not yet measured
The Results section, “Biomarker Changes from Baseline to Year 1” (page not provided), reports changes in inflammatory, lipid, and other biomarkers after one year of hormone therapy. This supports the point that hormone use can affect biomarker profiles, but the paper does not establish the claim specifically for both long-term and recent use. (LLM, conf=0.82)
- Partly supportedcites [43] de Sa Rosa e Silva, 2006, The levonorgestrel-releasing intrauterine device reduces CA-125 serum levels in patients with endometriosis, Fertil Steril sourceExperimental — accuracy not yet measured
The study reports that six months of levonorgestrel-IUD or GnRH-agonist treatment significantly reduced serum CA-125 in patients with endometriosis (results, pp. 742–744). This supports an effect of sustained hormone treatment on one biomarker, but does not establish an effect of recent hormone use or changes across biomarker profiles more broadly. (LLM, conf=0.85)

“Current BMI has been shown to be inversely associated with endometriosis (66) and validly measured by self-reported questionnaire (67–69).”

The Results report that self-reported BMI was within two BMI units of measured BMI for 81.5% of adults, supporting its usefulness as an approximate measure. But the Discussion reports substantial misclassification at the high and low ends of the BMI scale, and the Conclusion qualifies its use for estimating health risks on correcting for demographic biases. The unqualified claim that current BMI is validly measured by questionnaire overstates the paper. (LLM, conf=0.88)
- Could not verifycites [69] Spencer, 2004, Accuracy of self-reported waist and hip measurements in 4492 EPIC-Oxford participants, Public Health Nutr sourceExperimental — accuracy not yet measured
The Participants and methods section calculates BMI from measured height and weight; the study validates self-reported waist and hip measurements, not questionnaire-based BMI. The Discussion mentions an earlier comparison of self-reported and measured BMI and notes greater underestimation among heavier participants, but does not establish that self-reported BMI is valid.

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.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
