Air pollution and respiratory outcomes in COPD above and below current environmental protection agency standards.
Article in Environmental epidemiology (Philadelphia, Pa.), 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: Rigorous studies are needed to defend the current National Ambient Air Quality Standards and prompt policymakers to acknowledge a dose-response relationship between air pollution and respiratory outcomes. In the most recent Environmental Protection Agency comprehensive review, scientists determined there was insufficient evidence to claim a causal relationship between chronic particulate matter air pollution (PM Methods: This study examined the associations between chronic PM Results: For every 10 μg/m Conclusions: These findings add rigorous evidence to support the continuation of the current annual PM
