Prehospital prediction of survival after out-of-hospital cardiac arrest using point-of-care testing and vital signs: a prospective, multinational study.
Article in Scientific reports, 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
Prehospital vital signs and point-of-care testing (POCT) analytical biomarkers may have the potential to predict the outcome in out-of-hospital cardiac arrest (OHCA). The aim was to develop the first score for predicting survival to hospital discharge (STHD) based on the combination of prehospital vital signs and POCT physiologic parameters. A prospective, multinational and ambulance-based study was conducted in OHCA patients with return of spontaneous circulation (ROSC) managed by emergency medical services and transferred with high priority to the emergency department. The vital signs and analytical biomarkers were obtained post-ROSC. A total of 203 OHCA patients with ROSC from two cohorts were used. The predictive score was based on the lactate, Glasgow Coma Scale (GCS) score, creatinine, mean arterial pressure (MAP), pulse oximetry saturation/fraction of inspired oxygen ratio (SaFi), pH and potassium. The discriminative power in terms of area under the curve (AUC) were 0.937 (95%CI:0.878–0.995) and 0.892 (95%CI:0.776-1) in the Spanish and Austrian cohorts, respectively. A combination of prehospital vital signs and POCT biomarkers shows potential for predicting STHD in this preliminary analysis. However, given the small size of the external validation cohort, the score requires further large-scale, prospective validation before any conclusions regarding clinical implementation can be drawn. At its current stage of development, the score is not ready for clinical use.
