Bibliographic record
Abstract
Trivedi DP, Doll R, Khaw KT. Effect of four monthly oral vitamin D 3 (cholecalciferol) supplementation on fractures and mortality in men and women living in the community: randomised double blind controlled trial. BMJ2003 ; 326 : 469 –72 [OpenUrl][1][Abstract/FREE Full Text][2] QUESTION: Does oral vitamin D3 (cholecalciferol) supplementation reduce the incidence of fractures in community dwelling elderly people 65–85 years of age? Randomised (unclear allocation concealment), blinded (participants and clinicians), placebo controlled trial with 5 years of follow up. Community based study with participants recruited from the British Doctors Study register and a general practice register in Suffolk, UK. 2686 elderly people 65–85 years of age (mean age 75 y, 76% men) who were living in the general community. Exclusion criteria included current use of vitamin … [1]: {openurl}?query=rft.jtitle%253DBMJ%26rft.stitle%253DBMJ%26rft.aulast%253DTrivedi%26rft.auinit1%253DD.%2BP%26rft.volume%253D326%26rft.issue%253D7387%26rft.spage%253D469%26rft.epage%253D469%26rft.atitle%253DEffect%2Bof%2Bfour%2Bmonthly%2Boral%2Bvitamin%2BD3%2B%2528cholecalciferol%2529%2Bsupplementation%2Bon%2Bfractures%2Band%2Bmortality%2Bin%2Bmen%2Band%2Bwomen%2Bliving%2Bin%2Bthe%2Bcommunity%253A%2Brandomised%2Bdouble%2Bblind%2Bcontrolled%2Btrial%26rft_id%253Dinfo%253Adoi%252F10.1136%252Fbmj.326.7387.469%26rft_id%253Dinfo%253Apmid%252F12609940%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/ijlink?linkType=ABST&journalCode=bmj&resid=326/7387/469&atom=%2Febnurs%2F6%2F4%2F113.atom

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.
