Abstract
E Burleigh Dr E Burleigh, Victoria Infirmary, Glasgow, UK; Liz.Burleigh@sgh.scot.nhs.uk In elderly hospital inpatients, does vitamin D plus calcium prevent falls more than calcium alone? ### Design: randomised controlled trial. ### Allocation: concealed. ### Blinding: blinded (patients, {clinicians, data collectors, data analysts, and outcome assessors}*). ### Follow-up period: until discharge, transfer to another unit, or death (median hospital stay 30 d). ### Setting: an acute geriatric unit in a UK hospital. ### Patients: 205 inpatients (median age 84 y, 59% women, 85% had a history of falls) who were ⩾65 years of age and newly transferred or admitted to general assessment or rehabilitation wards. Exclusion criteria included known hypercalcaemia, urolithiasis, renal dialysis therapy, terminal status, bed-bound with a reduced Glasgow Coma Scale, current use of calcium and vitamin D supplements, and designation of “nil …

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.
