Characteristics and outcomes of out-of-hospital cardiac arrest due to drowning - a nationwide registry-based study.
Article in Scandinavian journal of trauma, resuscitation and emergency medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
aim of the studyTo describe and compare cases of resuscitation after out-of-hospital cardiac arrest (OHCA) attributed to drowning (D-OHCA) versus other causes (ND-OHCA).
methodsRetrospective, descriptive and comparative analysis of D-OHCA vs. ND-OHCA patients registered in the German Resuscitation Registry from January 2013 to December 2023 using Chi-square, Mann-Whitney U tests and regression analysis. Key variables included 10-year age groups, body temperature measured at the scene, prehospital factors (e.g., bystander CPR, initial rhythm), and outcomes such as survival and neurological status (CPC, mRS) at hospital discharge.
resultsOf the 68,719 included patients 316 (0.5%) had D-OHCA with 50% of the cases occurring during the summer months (June, July and August). D-OHCA in comparison to ND-OHCA patients were younger (median age 50 years vs. 72.5 years, p < 0.001), had a higher rate of asystole as initial rhythm (73.1 vs. 54.9%, p < 0.001) and a lower initial body temperature (median of 31.1 °C vs. 35.8 °C, p < 0.001). While overall survival and favourable neurological outcomes did not differ significantly between groups, stratified analysis showed that D-OHCA patients aged 0-10 years had significantly higher survival rates (44.7% vs. 16.3%, p < 0.001) and favourable neurological outcomes at hospital discharge (34.0% vs. 7.6%, p < 0.001) compared to ND-OHCA patients under 11 years.
conclusionDrowning was a rare cause of out-of-hospital cardiac arrest in this study, often occurring during summer months. Outcome in D-OHCA was generally comparable to ND-OHCA and only better in children aged up to 10 years. Lower body temperatures were associated with unfavourable outcomes in most D-OHCA cases.
