Abstract

Background: Endometriosis affects women of reproductive age. Increasing attention is being given to the characterization of comorbidities in endometriosis to enhance clinical phenotyping. Among these comorbidities, migraine has been reported to be significantly more common in individuals with endometriosis compared to the general population. However, the true epidemiological burden remains uncertain, and no conclusive evidence links specific subtypes of endometriosis to migraine.

Main body: Seven electronic databases were searched from inception until July 22nd, 2024, using combinations of relevant keywords. PROSPERO Registration CRD42023449492. Two independent reviewers screened the records according to inclusion/exclusion criteria and abstracted data. The risk of bias assessment was undertaken using the ROBINS-E tool. Random effects models were implemented to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between endometriosis and migraine. Fourteen studies were included in the qualitative synthesis, and 13 in the meta-analysis, accounting for a total of 331,655 individuals (32,489 with endometriosis vs. 299,166 controls). There was a serious risk of bias in the majority of the included studies, with 50% being at very high risk of bias. The risk of migraine was higher in individuals with endometriosis compared to those without (OR 2.25, 95%CI = 1.85-2.72; n = 13 studies; I2 = 81%). This association remained significant in the sensitivity…
