A population-based analysis of prognostic factors associated with survival in adult traumatic cardiac arrest patients.
Article in CJEM, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesHistorically, traumatic cardiac arrest studies have described poor survival rates and argued that resuscitation is futile. However, recent reports have demonstrated that survival rates may be higher than previously appreciated. Our objectives were to determine survival rates in traumatic cardiac arrest patients and assess for factors associated with survival to hospital discharge.
methodsWe conducted a registry review study of adult traumatic cardiac arrest patients (≥ 17 years old) in Nova Scotia over a 16-year period (2007-2023). Data were collected from the paramedic electronic Patient Care Record and the Nova Scotia Trauma Registry. The primary outcome was survival to hospital discharge. We compared characteristics between survivors and non-survivors and assessed for predictors of survival. Descriptive statistics, t-tests, chi-square analysis, and multivariable logistic regression models were used.
resultsA total of 1042 patients were included in the analysis. Ages ranged from 17 to 96 years (mean 50.03 ± 19.2), and 80.7% were male. Most injuries were blunt trauma (71.7%, 747/1042). The overall survival rate was 1.9% (20/1042). Compared to non-survivors, patients who survived to hospital discharge had lower mean Injury Severity Score (17.8 ± 11.1 vs. 34.4 ± 21.3, p < 0.001). On multivariate analysis, survival to discharge was associated with critical care transport (OR 27.16, 95%CI 7.32-103.86) and direct transport to final facility (OR 4.10, 95%CI 1.37-11.80), while increasing Injury Severity Score (OR 0.93, 95%CI 0.88-0.97) was associated with mortality.
conclusionsSurvival to hospital discharge was observed in 1.9% of traumatic cardiac arrest patients. Critical care transport and direct transport to the final facility were associated with patient survival. The identified predictors of survival may help inform prehospital triage and resuscitation strategies for patients experiencing traumatic cardiac arrest.
