Assessing accessibility to the extracorporeal cardiopulmonary resuscitation pathway for out-of-hospital cardiac arrests in London.
Article in Resuscitation plus, 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
Aims: Extracorporeal cardiopulmonary resuscitation (ECPR) may improve outcomes in selected patients with refractory out-of-hospital cardiac arrest (OHCA), but timely access is essential. In Greater London, a prehospital ECPR pathway enables transport of eligible patients to extracorporeal membrane oxygenation (ECMO)-capable centres within a target arrest-to-arrival interval of 45 min. We quantified accessibility to this pathway and explored how alternative service configurations might influence access. Methods: This retrospective, observational study analysed five years of routinely collected OHCA data from the London Ambulance Service to identify patients meeting the ECPR eligibility criteria. Using pathway modelling and geospatial analysis we estimated the proportion of patients able to reach an ECMO-capable centre within 45 min and evaluated potential strategies for improving access. Results: 776 patients were identified as being eligible for the prehospital ECPR pathway, but only 3% ( Conclusion: Accessibility to the prehospital ECPR pathway appears limited. Modifications to operational parameters, particularly extending time thresholds and operating hours, could substantially increase access. These findings have important implications for the design and optimisation of ECPR services in urban medical systems.
