Mariya Stavnichuk

Mariya Stavnichuk is the first author of a widely cited 2020 systematic review and meta-analysis of bone loss in space travelers, published in npj Microgravity with senior author Svetlana V. Komarova (bone-biology group at McGill University / Shriners Hospital for Children, Montreal). The paper pools spaceflight bone-density data across missions from Gemini through ISS and across imaging methods, and is the source of the figure this vault treats as canonical: lower-limb bone-mineral-density loss of about −0.8% per month on missions longer than 30 days.

Matters to this vault as the eponym of "the Stavnichuk meta-analysis" — the document the bed-rest-analog thread repeatedly leans on for the spaceflight-side reference numbers against which the ground analog and the matched pQCT comparison are judged.

Note (2026-08-15): hub created during the Stavnichuk–Böcker bridge promotion. The Stavnichuk 2020 meta-analysis anchors this vault's most-quoted spaceflight bone-loss figure yet had no author entity page, while the parallel Böcker 2026 paper already had one (entity-jorn-rittweger). Senior author Svetlana V. Komarova is flagged as a further owed hub in 00-meta/seek-flags.md rather than created here.
