Abstract
Aim Out-of-hospital traumatic cardiac arrests (TCA) are associated with a poor prognosis, yet limited research focuses on paediatric TCA. This study aimed to compare outcomes following TCA between children and adults. Methods We conducted a retrospective cohort study using data from the French cardiac arrest registry (RéAC) between July 2011 and March 2023. We included all patients under 65 years who suffered a TCA managed by a mobile medical team. Patients were categorized as children (<18 years) and adults (18–65 years). The primary endpoint was the 30-day survival, and secondary endpoints were: return of spontaneous circulation (ROSC), survival at hospital admission and survival with a favourable neurological outcome (Cerebral Performance Categories 1–2) at 30 days. Results Among 5,030 included patients, 396 were children (median age 13 [IQR 4–16] years; 73.2% male) and 4,634 were adults (median age 39 [IQR 27–51] years; 80.4% male). Paediatric patients had significantly higher rates of ROSC (25.5% vs. 20.6%, p = 0.02), survival to hospital admission (21.2% vs. 14.7%, p < 0.001), and 30-day survival (3.5% vs. 1.6%, p < 0.01). However, the proportion of patients achieving a favourable neurological outcome at 30 days did not differ significantly between groups (0.8% vs. 0.9%, p = 0.80). Conclusions Paediatric patients with out-of-hospital TCA demonstrate higher rates of ROSC and survival compared to adults, although neurological outcomes remain poor in both populations. These findings underscore age-related disparities in TCA prognosis and highlight the need for age-specific research in TCA patients.

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 it
