Shadows in the Air: Mental health vulnerabilities under PM10 and PM2.5, before and after COVID-19.
Article in SSM - population health, 2025. 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
Air pollution is an increasing public health concern, with evidence indicating that poor air quality adversely affects health through various pathways. However, its impact on mental health remains underexplored despite indications of pollutant-induced distress. This study examines the causal relationship between air pollution and mental health disorders-such as depression, sleep disorders, ADHD, and OCD-in South Korea. Assessing this relationship is challenging due to the simultaneous occurrence of economic growth, rising stress, and worsening air quality. Additionally, mental health issues have risen despite declining pollution levels post-COVID-19, further complicating the analysis. To address these challenges, we use wind speed and direction as instrumental variables. Our results show significant adverse effects of air pollution on mental health, particularly before 2020. Although the impact diminishes post-pandemic with improved air quality, certain demographic groups remain vulnerable. This study underscores the need for policies safeguarding mental health in at-risk groups, regardless of declining average pollution levels, and contributes to the literature by highlighting effects on less-studied disorders such as ADHD and OCD.
