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
objectivesTo explore the association of intra-arrest sodium bicarbonate (SB) use with outcomes in pediatric in-hospital cardiac arrest (p-IHCA) when accounting for the timing of initial SB administration. We hypothesized that administration of SB within the first 5 minutes of p-IHCA would be associated with greater odds of hospital survival and return of spontaneous circulation (ROSC).
designRetrospective cohort study.
settingQuaternary care academic children's hospital. PATIENTS: Children 18 years old or younger with pulseless IHCA of at least 5 minutes duration at our institution between January 2013 and January 2023 with complete data were included.
interventionsNone. MEASUREMENTS AND MAIN
resultsOf 243 index events of p-IHCA, 99 (41%) received SB in the first 5 minutes of cardiopulmonary resuscitation (CPR). Overall, 107 patients (44%) survived to hospital discharge and ROSC was achieved in 91 of 243 patients (37%). A logistic treatment-effects estimation utilizing inverse-probability weighting via a propensity score was performed to compare the effects of SB use within the first 5 minutes of CPR with those who did not receive early SB. In this analysis, we failed to detect an association between early SB, compared with not, and differing adjusted odds of survival to discharge (adjusted odds ratio [aOR], 0.87; 95% CI, 0.45-1.69; p = 0.687) and ROSC (aOR, 0.82; 95% CI, 0.43-1.56; p = 0.537).
conclusionsIn this retrospective cohort study of p-IHCA, we failed to detect an association between timing of SB and odds of survival to hospital discharge and ROSC. These findings warrant reevaluation of the evidence and support a less restrictive recommendation for SB use during p-IHCA in U.S. national guidelines.
