Prior studies have been limited in generalizability and did not use an active comparator as a control. The current matched case\u2013control study utilized a bootstrapped sampling design, matching 241 CM cases with controls (i.e., women diagnosed with non-meningioma brain, breast, or skin tumor, one control per type for three total) on age \u00b1 5 years and diagnosis date \u00b1 3 months. Conditional logistic regression was used to estimate odds ratios (ORs) compared with an active (norethindrone or levonorgestrel) and non-active control group. Exposure to dMPA at any time point was not associated with the diagnosis of cerebral meningioma (OR 1.75, 95% CI 0.81\u20134.95). Exposure to dMPA within a year of diagnosis was associated with the diagnosis of CM compared to both an active control (OR 3.38, 95% CI 1.13\u20139.70) and a non-active control (OR 6.90, 95% CI 2.31\u201317.58). This association was also present for those who were exposed within two years prior when compared to a non-active control (OR 3.54, 95% CI 1.50\u201311.88) but not an active control. Combined with the prior literature, the current results suggest that future research is warranted to understand this association.<\/jats:p>","DOI":"10.3390\/curroncol32070401","type":"journal-article","created":{"date-parts":[[2025,7,14]],"date-time":"2025-07-14T09:56:54Z","timestamp":1752487014000},"page":"401","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Matched Case-Control Study Examining the Association Between Exposure to Depot Medroxyprogesterone Acetate and Cerebral Meningioma Using an Active Comparator"],"prefix":"10.3390","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5004-7996","authenticated-orcid":false,"given":"Russell","family":"Griffin","sequence":"first","affiliation":[{"name":"Department of Epidemiology, School of Public Health, University of Alabama at Birmingham, Birmingham, AL 35294, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"Arend","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Heersink School of Medicine, University of Alabama at Birmingham, Birmingham, AL 35294, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,13]]},"reference":[{"key":"ref_1","unstructured":"(2024, December 17).
