Epinephrine Before Defibrillation in Children With Initially Shockable In-Hospital Cardiac Arrest.
Article in Critical care medicine, 2025. 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
objectiveAssess prevalence of epinephrine before or during the same minute as defibrillation and association with clinical outcomes in pediatric in-hospital cardiac arrest (IHCA).
designRetrospective cohort study.
settingWe used 2000-2020 data from the American Heart Association's Get With the Guidelines-Resuscitation Registry. PATIENTS: Children (< 18 yr) with index IHCA with an initial shockable rhythm of ventricular fibrillation or pulseless ventricular tachycardia and at least one defibrillation attempt.
interventionsNone. MEASUREMENTS AND MAIN
resultsThe primary exposure was epinephrine administration before or during the same minute as defibrillation. Study outcomes were survival to hospital discharge (primary outcome), return of spontaneous circulation (ROSC) for greater than or equal to 20 min, and survival with favorable neurologic outcome. Propensity-score matching was used for confounding adjustment. Among 492 pediatric IHCA index events with an initial shockable rhythm, median age was 7 years and 351 (71%) were in the ICU. Overall, 232 (47%) children received either epinephrine before defibrillation (29%) or during the same minute as defibrillation (18%). In unadjusted analyses, proportions of survival to hospital discharge (37.1% vs. 51.2%), ROSC (74.6% vs. 84.6%), and survival with favorable neurologic outcome (22.1% vs. 40.4%) were lower in the epinephrine before or during the same minute as defibrillation group. However, in adjusted analyses using propensity score matching with exact matching on time to defibrillation category, epinephrine before or during the same minute as defibrillation was not associated with hospital survival (odds ratio [OR] 0.84, 0.46-1.56), ROSC (OR 0.97, 0.48-1.96), or favorable neurologic outcome (OR 0.52, 0.27-1.00).
conclusionsContrary to current guidelines, nearly 50% of pediatric IHCA due to an initial shockable rhythm receive epinephrine before, or during the same minute, as first defibrillation. Although survival outcomes were numerically lower in epinephrine before defibrillation group, the association was not statistically significant.
