Association between acute exacerbation of chronic obstructive pulmonary disease and short-term exposure to ambient air pollutants in France.
Observational study in Environmental health : a global access science source, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03079661 (Impact of Air Quality on Exacerbations of COPD in the Somme), which is not on this map. Cited by 5 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.

Abstract
backgroundAmbient air pollution is recognized as a major risk factor for chronic obstructive pulmonary disease (COPD) which is the third leading cause of death worldwide. We examined whether variations in daily outdoor air pollutants levels were associated with excess hospital emergency room visits (ERV) for acute exacerbation of COPD (AECOPD).
methodsThis two-center ecological cohort study was conducted in Amiens, France. We collected all consecutive ERV for AECOPD throughout 2017 and developed single pollutant models to assess the association between AECOPD and nitrogen dioxide (NO
resultsWe recorded 240 ERV among 168 COPD patients in 2017 and identified 9 peaks of ERV. There was a statistically significant positive correlation between the daily ERV for AECOPD and the daily average concentrations of PM
conclusionEven though the pollution levels measured generally remained below or near the 2021 short-term air quality guidelines issued by the World Health Organization, significant aggregate-level associations were found between severe AECOPD leading to ERV and daily concentrations of PM CLINICAL
