Playground equipment injuries at home versus those in public settings: differences in severity
Bibliographic record
Abstract
The objective of the present research was to compare the severity of playground-related injuries in backyards of home with those occurring in public settings. This case-control study used emergency-based surveillance data from Canada regarding children, 3-11 years old, who were injured after falling from playground equipment (PGE). Cases were those whose injuries occurred at home (backyards), and controls were those whose injuries occurred in parks, schools or daycare centres. Of the 39,730 subjects selected, 84% happened in public and 16% at home. Children falling from a home PGE had greater odds of severe injuries (OR=1.30; 95% CI 1.23 to 1.37) and fractures (OR=1.47; 95% CI 1.39 to 1.55) than those from public PGE. Children aged 3-5 years falling off slides at home, compared to slides in public settings, had the greatest odds of severe injuries (OR=1.72; 95% CI 1.41 to 2.09) and fractures (OR=2.17; 95% CI 1.79 to 2.64.) When setting up PGE at home, parents should be diligent in using proper landing surfaces, such as those found in public playgrounds.

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.
