The Association Between the Eosinophilic COPD Phenotype with Overall Survival and Exacerbations in Patients on Long-Term Non-Invasive Ventilation.
Article in Biomolecules, 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
backgroundLong-term non-invasive ventilation (LT-NIV) can prolong life expectancy and may reduce the number of exacerbations in patients with COPD. The eosinophilic phenotype has recently gained significant attention as a treatable trait in COPD. However, it is less known how this phenotype relates to exacerbations and mortality in patients who are set up on LT-NIV.
methodsA total of 191 patients with COPD (65 ± 8 years, 55% women) who were setup on LT-NIV and followed-up (28/15-49/months) at our tertiary centre were analysed. The eosinophilic phenotype was defined by using an accepted cutoff for blood eosinophil count (≥300 cells/µL).
resultsA total of 37 patients had the eosinophilic phenotype (66 ± 9 years, 60% women). There was a higher reduction in the number of exacerbations (1.0/-1.0-3.2/ vs. 0.05/-1.4-1.63/,
conclusionsThe eosinophilic COPD phenotype seems to show better clinical responses to long-term NIV than patients without this trait. Further mechanistic studies are warranted to analyse this association.
