Long-term exposure to ambient air pollutant and acute exacerbations of chronic obstructive pulmonary disease: a retrospective cohort study in Xinjiang, China.
Article in Frontiers in public health, 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
Introduction: While short-term ambient air pollution is implicated in chronic obstructive pulmonary disease (COPD) exacerbations, evidence for chronic exposure remains limited, particularly in vulnerable subgroups. This study evaluates longitudinal associations between major air pollutants and acute exacerbations (AEs), while identifying high-risk demographic and clinical subgroups. Methods: We analyzed 660 COPD patients from People's Hospital of Xinjiang (2020-2023). Annual average concentrations of PM Results: Long-term ozone exposure demonstrated significant AE risk elevation (OR = 1.007, Conclusion: This study establishes chronic ozone exposure as an emerging environmental determinant of COPD exacerbations, with disproportionate impacts on vulnerable subgroups. Our findings demand urgent integration of ozone mitigation into national respiratory health strategies and precision public health approaches to address environmental health inequities.
