Abstract

fetched live from OpenAlex

Why Cochrane should prioritise sharing data Open sharing is vital for collaboration, innovation, and reproducibility: Cochrane could show leadership.Packer 1 discusses that the one who submits a research for public good should be ready to receive a request for data sharing for examination and re-analysis and tax payers assume that a national agency is checking such data and analysis.Here we discuss Cochrane's practice on data sharing.Open science, as endorsed by the G7, 2 includes sharing data, computer code and materials.It is essential for reproducibility, collaboration, and innovation.We support the work of Cochrane, but are concerned Cochrane is not sharing all its reviews' data.These data should be fully accessible for re-use by third parties.Cochrane, a non-profit private company 3 and registered charity, produces and maintains systematic reviews in health and social care.Its work is undertaken by a global network of thousands of people, 4 and its support largely comes from public funding.5 Most people producing Cochrane reviews are volunteers, not specifically funded for this work 6 7 and Cochrane encourages 'crowdsourcing' of work.[8][9][10] Cochrane Editorial bases help volunteers obtain study reports and manually extract the wealth of data needed to generate systematic reviews.[11][12][13] Cochrane teams use RevMan software 14 to produce files in standard format (XML), storing information on the studies, their methods and results for publication in the Cochrane Library.

Not 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.
