Endotracheal tube exchange in preterm infants with evolving chronic lung disease: safety, outcomes, and impacts on pulmonary mechanics.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2026. 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
objectiveA study of the safety of endotracheal tube exchange and its impact on pulmonary mechanics in preterm infants with chronic lung disease. STUDY
designThis retrospective cohort study included 67 infants born at less than 29 weeks gestational age who underwent endotracheal (ETT) exchange after 28 days of life in a Level 4 NICU between 2017 and 2023. Descriptive analysis was performed using the Wilcoxon rank-sum test and Chi-squared or Fisher's exact tests to characterize the cohort and compare variables before and after the ETT exchange.
resultsETT exchange led to increased stability in 60% of cases, while adverse events occurred in 57% of exchanges. By 36 weeks postmenstrual age, 92% of the cohort developed type 2 or 3 bronchopulmonary dysplasia (BPD).
conclusionThe majority of ETT exchanges resulted in increased stability; however, the adverse event rate was high. Further studies are needed to determine whether ETT exchange improves long-term outcomes.
