Childhood Fracture Begets Childhood Fracture: A Population-based Study of Longitudinal Fracture Patterns in Ontario Children
Bibliographic record
Abstract
Objectives: The objectives of this study were two-fold: (1) to describe the epidemiology of childhood fractures in Ontario; (2) to determine if having a fracture in childhood is associated with an increased risk of having a future fracture. Methods: This was a population-based retrospective cohort study using Ontario health administration data. Children aged 0 to 15 years were grouped according to baseline fracture status. Associations between predictors and future fracture were assessed using Poisson and Cox PH regression. Results: 43,154 Ontario children experienced a baseline fracture (17.5 per 1000 child years). Children with a baseline fracture had a 60% higher rate of fracture during 7 years of follow-up after adjustment for sex, rurality, history of previous fracture and the occurrence of head injury and soft-tissue injury. Conclusions: The occurrence of a baseline fracture is associated with an increased rate of future fracture irrespective of age at time of baseline fracture.

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; both teacher heads agree on what is shown here.
