Prehospital predictors of clinical outcomes in out-of-hospital cardiac arrest with pulseless electrical activity: a JCS-ReSS report.
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
Background: Out-of-hospital cardiac arrest (OHCA) with pulseless electrical activity (PEA) has a poor prognosis and is aetiologically heterogeneous. We aimed to identify prehospital predictors of a favourable outcome, overall and by presumed aetiology. Methods: This nationwide cohort study analysed 442,630 adults with OHCA and an initial rhythm of PEA from the All-Japan Utstein Registry between 2005 and 2024. The primary outcome was a favourable neurological outcome at 1 month. Two models were fitted, at the scene and at hospital arrival, each also within each aetiology. Epinephrine and advanced airway management (AAM) were assessed by time-dependent propensity score sequential matching. Results: At the scene, a witnessed arrest (risk ratio [RR], 1.65) predicted a favourable neurological outcome, and a longer response time predicted a worse one (RR, 0.66; 10 versus 5 min). The gradient with age was steeper in cardiac than non-cardiac PEA (RR, 0.38 versus 0.78). At hospital arrival, prehospital return of spontaneous circulation (RR, 23.31) was the strongest predictor, but conversion to a shockable rhythm predicted a favourable outcome only in cardiac PEA and a worse outcome in non-cardiac PEA (RR, 1.37 versus 0.73). Standardised to a common covariate distribution, 1-month survival was higher in non-cardiac PEA, whereas a favourable neurological outcome was more likely in cardiac PEA. After time-dependent adjustment, the apparent harm from epinephrine and AAM was attenuated. Conclusions: Prehospital information available before hospital arrival predicted a favourable neurological outcome, but its prognostic meaning depended on the presumed aetiology. These independent prehospital predictors could inform future risk stratification.
