Gene signature linked to inhaled corticosteroid-induced lung function improvement in COPD: insights from the GLUCOLD Study.
Article in ERJ open research, 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
Rationale: COPD is characterised by chronic airflow limitation and persistent inflammation. Inhaled corticosteroids (ICS) are often used to reduce airway inflammation in patients. However, the response to ICS treatment varies among patients, and blood eosinophils may not fully reflect treatment effectiveness. In this study, we aim to identify gene modules associated with ICS responsiveness and assess the underlying biological pathways. Methods: We included 55 patients from the GLUCOLD study with mild-moderate COPD treated with ICS for 6 months with available gene expression data from biopsies. Treatment response was defined as changes in post-bronchodilator forced expiratory volume in 1 s (FEV Results: We identified four gene modules associated to ICS-induced improvement in FEV Conclusion: This study identified gene modules and pathways associated with ICS responsiveness in COPD, providing a potential mechanistic explanation for the variability in ICS treatment responsiveness in COPD.
