Abstract
OBJECTIVE: This study was a prospective validation of the Ottawa Ankle Rules (OAR) in Australia following appropriate education in the use of the rules. METHODS: The OAR were applied to consecutive patients 18 years and over presenting with acute ankle and foot injuries to the ED of an urban teaching hospital. RESULTS: Three hundred and thirty-three patients had 366 injuries. There were 43 fractures in 265 ankle injuries and 14 fractures in 101 foot injuries. Sensitivity was 100% for ankle (95% confidence interval (CI): 92-100) and midfoot fractures (95% CI: 77-100). Specificity was 15.8% (95% CI: 11-21) for ankle fractures and 20.7% (95% CI: 13-31) for midfoot fractures. CONCLUSION: The OAR had a sensitivity of 100% for ankle and midfoot fractures when used by both junior and senior physicians.

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.
