Rodeo Catastrophic Injuries and Registry: Initial Retrospective and Prospective Report
Bibliographic record
Abstract
OBJECTIVE: To introduce the Rodeo Catastrophic Injury Registry (RCIR) and quantify the nature and incidence of catastrophic injury and fatality in rodeo participants across North America. DESIGN: Retrospective and prospective collection of catastrophic and fatal injury data in rodeo using an online registry (RCIR). SETTING: Canada and the United States. PARTICIPANTS: North American rodeo competitors. ASSESSMENT OF RISK FACTORS: Age, gender, level of competition, rodeo event, mechanism of injury, and use of protective equipment. MAIN OUTCOME MEASURES: Frequency, incidence, and nature of catastrophic injuries and fatalities among rodeo participants. RESULTS: The incidence rate of catastrophic injury from 1989 to 2009 was 9.45 per 100 000 (49/518 286). The incidence rate of catastrophic injury during the 2007-2009 study period was 19.81 per 100 000 (19/95 892). The incidence rate of fatality from 1989 to 2009 was 4.05 per 100 000 (21/518 286). The incidence rate of fatality for the 2007-2009 study period was 7.29 per 100 000 (7/95 892). CONCLUSIONS: Thoracic compression mechanisms of injury are most pervasive and likely to be fatal in rodeo and bull riding. It is unknown whether rodeo protective vests have a protective effect in reducing catastrophic and fatal injuries. On the contrary, helmet use in bull riding and rodeo events seems to have a protective effect in reducing both catastrophic injury and fatality.

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.
