Success and safety of neonatal endotracheal tube exchanges: a NEAR4NEOS multicentre retrospective cohort study.
Observational study in Archives of disease in childhood. Fetal and neonatal edition, 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
objectivesTo compare success and safety of endotracheal tube (ETT) exchanges with primary intubations and identify factors associated with ETT exchange outcomes.
designRetrospective observational study of prospectively collected National Emergency Airway Registry for Neonates data. ETT exchanges are the placement of a new ETT when one is already in place, whereas primary intubations do not have a pre-existing ETT. The primary outcome was first-attempt success. Secondary outcomes included number of attempts, adverse tracheal intubation-associated events (TIAEs), severe TIAEs, desaturation and bradycardia. Descriptive statistics compared characteristics for ETT exchanges and primary intubations. Univariable and multivariable analyses compared primary and secondary outcomes and identified factors independently associated with ETT exchange outcomes.
resultsA total of 1572 ETT exchanges and 9999 primary intubations across 21 sites were included from October 2014 to September 2022. ETT exchanges represented 2.3%-31.2% (mean 13.6%) of intubations across sites. Patient, provider and practice characteristics varied significantly between ETT exchanges and primary intubations. In univariable analyses, ETT exchanges were associated with higher first-attempt success (70.5% vs 53.6%; p<0.001) and fewer safety events. In multivariable analyses, ETT exchanges were associated with an increased adjusted OR (aOR) of first-attempt success (1.71; 95% CI 1.57 to 1.86; p<0.001). ETT exchanges were associated with lower aOR of all safety outcomes except severe TIAEs. Factors independently associated with ETT exchange first-attempt success included video laryngoscopy and paralytic premedication.
conclusionCompared with primary intubations, ETT exchanges were associated with higher first-attempt success and fewer safety events. Video laryngoscope and paralytic premedication were associated with improved ETT exchange outcomes.
