Abstract
R G Cumming Dr R G Cumming, Concord Hospital, Concord, New South Wales, Australia; bobc@health.usyd.edu.au Does a 16-week, community-based tai chi programme reduce falls in healthy older adults? ### Design: randomised controlled trial. ### Allocation: unclear. ### Blinding: unclear if blinded. ### Follow-up period: 24 weeks. ### Setting: community in Sydney, New South Wales, Australia. ### Participants: 702 people ⩾60 years of age (mean age 69 y, 84% women) who lived in the community and had not practised tai chi in the previous year. Participants with degenerative neurological conditions, dementia, severely debilitating stroke, severe arthritis, marked vision impairment, or inability to walk across a room unaided were excluded. ### Intervention: a 16-week tai chi programme (n = 353) or a 24-week wait list (n = 349). The tai chi programme comprised weekly …

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
