Helicopter vs. ground transport: outcomes of out-of-hospital cardiac arrest patients with intra-arrest transport.
Article in Wiener klinische Wochenschrift, 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
objectiveDeciding to transport a patient intra-arrest is difficult. The effect of the mode of transportation, either helicopter emergency medical services (HEMS) or ground emergency medical services (GEMS) and its potential link to neurological outcomes has not yet been assessed.
methodsWe performed a retrospective cohort study using data from our Cardiac Arrest Registry. Adult out-of-hospital cardiac arrest (OHCA) patients transported intra-arrest were included. Neurological outcome at 6 months, measured using the cerebral performance category (CPC 1-2: good, CPC 3-5: poor), served as the primary endpoint. Associations between mode of transport and prehospital time with neurological outcome were examined using univariable and multivariable logistic regression.
resultsWe included 639 patients of whom 533 (83%) were transported by GEMS and 106 (17%) by HEMS. Patients transported by HEMS were younger (median age 54 years vs. 58 years) and more frequently had witnessed arrest and a shockable initial rhythm (55% vs. 42%). Median prehospital time did not differ significantly between groups (HEMS: 62 min, GEMS: 58 min). In univariable and multivariable analyses, the transport mode was not associated with a favorable neurological outcome at 6 months (p > 0.4). Neurological outcome was independently associated with arrest-related factors, including age, witnessed arrest, initial rhythm and cumulative adrenaline dose.
conclusionFor patients undergoing intra-arrest transport, the mode of transport (HEMS vs. GEMS) was not significantly associated with neurological outcomes at 6 months. Neurological results appeared to be more influenced by arrest-related factors than by the transport method in this cohort.
