Unravelling the exposome of severe exacerbations of obstructive respiratory diseases in France.
Article in BMJ open respiratory research, 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
introductionUnderstanding the influence of environmental and socioeconomic factors, collectively known as the exposome, on severe exacerbation risks in chronic obstructive pulmonary disease (COPD) and asthma is crucial for enhancing patient care.
methodsWe assessed the impact of the exposome on COPD and asthma severe exacerbations in France between 2018 and 2022, combining data from the French National Hospital Discharge Programme de Médicalisation des Systèmes d'Information database and open data for multiple environmental exposition. Using a retrospective matched case-control design, 473 990 patients with COPD and 187 332 patients with asthma were matched for sex, birth year and date of first hospitalisation. Conditional logistic regressions were performed to quantify ORs of exacerbations within the studied population.
resultsIn a multivariate model, exposure to extreme cold temperatures and exceeding WHO standards for nitrogen dioxide (NO
conclusionsThe study highlights how exposome factors influence bronchial diseases and underscores the benefit of open-access data for advancing research. COPD and asthma exacerbations account for numerous deaths and cost billions and will increase with global warming, identifying modifiable environmental risk factors, improving patient care and helping shape valuable public health policies.
