Impact of short-term exposure to ambient air pollution on cardiovascular disease outpatient visits: a time-series study in Yichang, China.
Article in Environmental health : a global access science source, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundRapid industrialization has exacerbated ambient air pollution in Yichang, China, posing cardiovascular health risks. This study evaluates the short-term impact of ambient air pollutants on cardiovascular disease (CVD) outpatient visits and assesses the effectiveness of environmental policies implemented post-2018.
methodsWe analyzed 510,831 CVD outpatient records alongside daily concentrations of PM
resultsShort-term exposure to NO₂ (lag05, RR = 1.253, 95% CI: 1.192-1.317), SO₂ (lag0, RR = 1.053, 95% CI: 1.011-1.096), and CO (lag01, RR = 1.063, 95% CI: 1.016-1.111) was significantly associated with increased cardiovascular disease outpatient visits. Concentrations of five major ambient air pollutants (excluding O₃) showed significant reductions after 2018 (P < 0.001). The associations of SO₂, CO, and PM₁₀ with CVD visits were attenuated after 2018. NO₂ effects were stronger in colder seasons and remained robust in two-pollutant models. No statistically significant associations were observed for PM₂.₅, PM₁₀, and O₃.
conclusionShort-term exposure to NO₂, SO₂, and CO demonstrated statistically significant positive associations with cardiovascular disease outpatient visits. Environmental policies reduced ambient air pollutant levels and attenuated health impacts, supporting continued air quality interventions.
