Shorter epinephrine dosing intervals and one-year survival after in-hospital pediatric cardiopulmonary resuscitation.
Observational study in Jornal de pediatria. 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
objectiveTo evaluate the association between the interval doses of epinephrine and one-year survival and one-year neurological prognosis after pediatric in-hospital cardiac arrest (IHCA).
methodsThis observational retrospective cohort study included pediatric patients (0-18 years) who experienced IHCA and received at least two doses of epinephrine from January 2015 to December 2022. Data were collected following the Utstein style. The mean interval between epinephrine doses was categorized as 〈 3, 3-5, or > 5 min. Primary outcome was one-year survival; secondary outcomes were survival to hospital discharge and one-year neurological prognosis, assessed by the Pediatric Cerebral Performance Category.
results194 patients were eligible. In the univariate adjusted analysis, patients who received epinephrine at intervals shorter than 3 min had a 2.3-fold increased chance of one-year survival (OR 2.3; 95 % CI 1.0-5.5; p = 0.042), although this association was not sustained in the multivariable regression. Longer intervals between epinephrine doses (OR: 0.71; 95 % CI 0.52-0.71; p = 0.03), continuous vasoactive drugs infusion prearrest (OR 0.1; 95 % CI 0.1-0.4; p < 0.001), longer resuscitation duration (OR 0.8; 95 % CI 0.7-0.9; p = 0.028), epinephrine doses (OR 0.68; 95 % CI 0.56-0.81; p < 0.001) were associated with reduced one-year survival. Neurological deterioration was observed in 6 (16.6 %) of the 36 patients after one year (p = 0.001). No association was found between epinephrine dosing intervals (OR 0.72; 95 % CI 0.16-3.14; p = 0.65) and neurological outcomes.
conclusionEpinephrine dosing interval was not independently associated with one-year survival after adjusted analyses. These findings underscore the complexity of pediatric resuscitation and support further multicenter prospective studies.
