From stress to success: using physiological data to predict cardiopulmonary resuscitation simulation performance.
Article in Frontiers in psychology, 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 and aim: Managing stress is critical in emergency medicine, where cardiopulmonary resuscitation (CPR) rely on team dynamics. Although subjective and physiological markers assess stress, few studies have examined their combined effects during CPR simulations. The influence of team role (leader vs. member) and whether physiological data can predict performance also remain underexplored. This study addresses these gaps. Methods: Thirty emergency residents attending the School of Emergency Medicine of the University of Padua (Italy) were recruited with previous certification in Advance Cardiac Life Support (ACLS) and randomly paired, each assigned to one of two roles: team leader (TL) or team member (TM). Randomization also considered baseline stress level (PSS-10). Each pair was then assigned to cardiac arrest with a shockable or non-shockable rhythm, including 2 min of uninterrupted chest compressions, following American Heart Association (AHA) guidelines. The data collected included CPR performance metrics (compression depth, rate, recoil). Physiological data were collected before, during, and after CPR using Empatica E4 and eSense, Heart rate (HR), Heart Rate Variability (HRV), Electrodermal Activity (EDA), and Skin conductance response (SCR). Results: Participants reported moderate baseline stress (PSS-10, VAS stress/anxiety). Baseline physiological measures were within normative ranges. ANOVA revealed a significant effect of group condition for HRV ( Conclusion: This study shows that simulated CPR scenarios trigger psychophysiological stress responses. Increased HRV, HR, and EDA indicate a challenge-type reaction, despite stable subjective ratings across team roles, suggesting a shared load, with TL sympathetic activation as a possible mediator of global team activation. Notably, a nonlinear link between SD1 and performance emerged, indicating autonomic flexibility relevance.
