Prospective Validation of the Ottawa Ankle Rules in a Deployed Military Population
Bibliographic record
Abstract
This study prospectively validated the Ottawa Ankle Rules (OAR) in patients presenting with acute ankle trauma to a deployed military clinic at Prince Sultan Air Base in Saudi Arabia. The treating physician determined whether the patient met OAR criteria. The decision to obtain radiographs was left to the discretion of the physician. All radiographs were read by a radiologist blinded to the study. Patients who were not evaluated by radiographs received follow-up in the orthopedic clinic or by telephone. Forty-five consecutive patients were enrolled over a 3-month period. Twenty-nine (64%) patients met the OAR criteria, 32 (71%) received radiographs, and 5 (11%) fractures were identified. All fractures were predicted by the OAR. The sensitivity of the OAR was 1.0 and specificity was 0.40. Negative predictive value was 1.0, positive predictive value was 0.17, likelihood ratio positive value was 1.67, and likelihood ratio negative value was 0.0. The OAR correctly predicted all ankle fractures in the military population studied.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
