The interplay between migraine, endometriosis and polycystic ovarian syndrome: A systematic review
Bibliographic record
Abstract
Background Migraine and gynecological conditions, such as endometriosis (EDM) and polycystic ovarian syndrome (PCOS), are highly prevalent among females and appear to influence each other, with a potential shared pathophysiological mechanism. Therefore, this study aims to provide a comprehensive summary of the current evidence regarding the relationship between migraine and EDM/PCOS from a clinical perspective. Methods A systematic review was conducted using four databases (MEDLINE(Pubmed), EMBASE (Elsevier), Web of Science and Cochrane Library) along with searches in the grey literature. The protocol was registered prospectively on the PROSPERO platform (CRD42024628010). The primary search was performed on 4 December 2024. Eligible studies included observational studies that compared two or more groups of females with migraine, EDM and/or PCOS diagnosis. The modified Newcastle-Ottawa Scale was used to assess the quality of the included studies. Data extraction was performed and results systematically analyzed. Results From an initial 408 identified studies, a final selection of 15 was analyzed (14 focused on EDM and 1 on PCOS) with a total of 289,519 individuals included. All selected studies achieved a score of 6 or higher on the mNOS. When comparing females with and without EDM, the prevalence of migraine reached up to 44.7%, with females affected with EDM having up to a five-fold increased risk of developing migraine (adjusted odds ratio = 5.35, 95% confidence interval = 2.11–16.4). When comparing females with and without migraine, a higher prevalence and risk of EDM was observed, with rates reaching 53.4% and an adjusted odds ratio up to 10.5 (95% confidence interval = 2.2–51.4). Mixed findings were found regarding the influence of EDM on migraine characteristics, as well as the impact of migraine in EDM-related symptoms and disease severity. Females with migraine and EDM exhibited higher scores in disability assessment tools (Headache Impact Test-6, 30-item Endometriosis Health Profile), suggesting a greater disease burden. Due to the limited data, no conclusions could be drawn regarding a link between PCOS and migraine. Conclusions Although further high-quality research is required to better understand the underlying mechanisms linking migraine, EDM and PCOS, the current evidence supports a significant association between migraine and endometriosis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
