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
purposeTo explore the impact of ambient air pollution on the health-related quality of life (HRQoL) of Chinese residents.
methodsAir pollutant exposure and HRQoL in 21,909 participants were analyzed using data from the 2022 Psychology and Behavior Investigation of Chinese Residents (PBICR-2022). Air pollutants included fine particulate matter (PM2.5), PM10, ozone (O3), nitrogen dioxide (NO2), and carbon monoxide (CO). HRQoL was measured using the EQ-5D-5L questionnaire, which comprises two sections: the EQ-5D descriptive system (assessing five dimensions: Mobility, Self-care, Usual Activities, Pain/Discomfort, and Anxiety/Depression) and the EQ visual analogue scale (EQ-VAS). The health utility score (HUS) was calculated based on responses to the descriptive system. Multivariate logistic regression and Tobit regression models were used to analyze the association between ambient air pollution exposure and HRQoL.
resultsPM2.5 (β = − 0.000891 per μg/m3), O3 (β = − 0.000510 per μg/m3), NO2 (β = − 0.001311 per μg/m3), and CO (β = − 0.050839 per mg/m3) were significantly negatively associated with HUS (all P < 0.05), among NO2 exhibited the strongest negative association with HUS. All five air pollutants linked to the dimensions of Mobility, Self-care, and Usual Activities (all P < 0.05), whereas no significant associations were observed with Pain/Discomfort and Anxiety/Depression. Subgroup analysis revealed significant inverse associations with HUS among smokers/drinkers (PM2.5, PM10, NO2), rural residents/individuals living with others (O3), and unmarried individuals (CO).
conclusionExposure to ambient air pollutants was significantly associated with impaired HRQoL among Chinese residents, particularly in the dimensions of Mobility, Self-care, and Usual Activities. Notably, PM2.5, O3, NO2, and CO exposure exhibited pronounced negative correlations with HUS. These findings provide significant implications for designing targeted air pollution mitigation strategies, which could effectively enhance population health and quality of life.
