Intubation Trends and Survival in Pediatric In-Hospital Cardiac Arrest.
Article in JAMA network open, 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
Importance: The optimal airway management during pediatric in-hospital cardiac arrest (IHCA) is unknown. Objective: To evaluate intubation trends during pediatric IHCA between 2000 and 2022, and determine the association of intra-arrest intubation with survival in a recent cohort of patients (2017-2022). Design, Setting, and Participants: This retrospective cohort study (analysis performed between June 2023 and October 2024) used data from the multicenter American Heart Association Get With The Guidelines-Resuscitation registry. Pediatric patients (<18 years) with IHCA from 2000 through 2022 were included. Exposure: Intra-arrest endotracheal intubation. Main Outcomes and Measures: The primary outcome was survival to hospital discharge. Intra-arrest intubation trends were assessed using nonparametric test for trend. A time-dependent propensity matched analysis assessed the association between intra-arrest intubation and hospital survival from 2017 through 2022. Each minute, patients intubated were matched with patients at risk of intubation using a propensity score, with forced matching on stratification variables and replacement of controls. Mixed-effects logistic regression assessed the association with survival outcomes, with subgroup analysis by age and illness category. Results: The cohort included 3262 pediatric patients with IHCA (median age, 12.0 [IQR, 3.0-83.8] months; 1775 [54.4%] male) with no advanced airway at CPR onset. Return of spontaneous circulation was attained in 2413 patients (74.0%), and 1748 (53.6%) survived to hospital discharge. The intubation rate decreased over time (33 of 39 [84.6%] in 2000 to 112 of 168 [66.7%] in 2022; P < .001). In the 2017-2022 cohort, intubation vs nonintubation in each minute of CPR was associated with decreased discharge survival odds in unadjusted analysis (odds ratio [OR], 0.18; 95% CI, 0.14-0.24; P < .001) but not after matching (adjusted OR, 1.18; 95% CI, 0.90-1.53; P = .23). In children aged 8 years or older, after matching, intubation compared with nonintubation in each minute was associated with increased odds of discharge survival (adjusted OR, 1.91; 95% CI, 1.09-3.33; P = .02). Conclusions and Relevance: In this cohort study of pediatric patients with IHCA between 2017 and 2022 without an advanced airway at the start of CPR, no association was identified between intra-arrest tracheal intubation and hospital survival after time-dependent propensity score matching. In subgroup analysis, intra-arrest intubation in children 8 years or older was associated with higher survival odds. These findings may have important clinical implications for clinicians caring for children with IHCA and warrant further investigation into the physiologic and practical mechanisms of this association.
