Immediate intravenous epinephrine versus early intravenous epinephrine for in-hospital cardiopulmonary arrest.
Article in BMC anesthesiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundIntravenous epinephrine has been a key treatment in cardiopulmonary arrest since the early 1960s. The ideal timing for the first dose of epinephrinee is uncertain. We aimed to investigate the association of immediate epinephrine administration (within 1-min of recognition of cardiac arrest) with return of spontaneous circulation (ROSC) up to 24-h.
methodsThis was a multicenter retrospective analysis of patients who underwent cardiopulmonary resuscitation. We included the following patients: 1) ≥18 years-old, 2) non-shockable rhythms, 3) received intravenous epinephrine during cardiopulmonary resuscitation, 4) witnessed in-hospital arrest and 5) first resuscitation attempt (for patients requiring more than one resuscitation attempt). We excluded patients who suffered from traumatic arrest, were pregnant, had shockable rhythms, arrested in the operating room, with Do-Not-Resuscitate (DNR) order, and patient aged 17 years-old or less.
resultsA total of 360 patients were included in the analysis. Median age was 62 years old and median epinephrine administration time was two minutes. We found that immediate epinephrine administration (within 1-min) is associated with higher rates of ROSC up to 24-h (OR = 1.25, 95% CI; [1.01-1.56]), compared with early epinephrine (≥2-min) administration. After adjusting for confounding covariates, earlier administration of epinephrine predicted higher rates of ROSC sustained for up to 24-h (OR 1.33 95%CI [1.13-1.55]).
conclusionsImmediate administration of epinephrine in conjunction with high-quality CPR is associated with higher rates of ROSC.
