Air pollution and chronic obstructive pulmonary disease-related health outcomes: a bibliometric and visualization analysis.
Article in Journal of thoracic disease, 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
Background: Air pollution is a critical environmental risk factor for chronic obstructive pulmonary disease (COPD). Although numerous studies have focused on investigating this aspect, a comprehensive bibliometric overview of the global research landscape, hotspots, and emerging trends remains lacking. This bibliometric analysis aimed to examine the status, hotspots, and frontiers of research on the effect of air pollution on COPD-related health outcomes to inform COPD prevention and management. Methods: Literature was retrieved from the Web of Science Core Collection (1964 to May 31, 2025), yielding 11,167 articles and reviews. Country/institution collaboration, journal co-citation, keyword clustering, and burst detection analyses were conducted using CiteSpace, VOSviewer, and the bibliometrix package in R. Results: The number of publications increased rapidly after 1990, with Conclusions: The bibliometric analysis results revealed that the relationship between air pollution and COPD-related health outcomes is an active research area, with major themes including disease burden, mortality, hospitalization, household air pollution, oxidative stress, and climate change.
