Impact of air pollution and asthma on school attendance and educational attainment: a scoping review.
Article in BMJ open respiratory research, 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
backgroundAsthma morbidity is high among young people, and studies have shown associations between asthma and school attendance and educational attainment. However, findings are unclear concerning associations between air pollution and these educational outcomes, and whether asthma might mediate any associations.
objectiveThis review aimed to summarise, and find gaps in, the research on outdoor air pollution, asthma and educational outcomes. To our knowledge, this is the first review to consider the impact of air pollution or asthma, individually or in combination, on the school attendance and educational attainment of children and young people.
designThis scoping review, using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews method, reports on searches for English language studies of air pollution, asthma and school attendance and educational attainment in eight databases with tabulation and synthesis of the extracted data.
resultsAssociation between air pollution and school absence was found to be weaker than for active asthma with this outcome. Uncontrolled asthma was associated with lower educational attainment, but findings on air pollution exposure were mixed. Two studies found associations for air pollution with poorer educational outcomes for young people with asthma. Long-term exposure to air pollution, and an increase in the frequency of peaks of air pollution, were associated with worse educational outcomes. Inequalities in access to healthcare and education were associated with uncontrolled asthma and lower educational outcomes. Only one study used linked health, environmental and educational data.
conclusionsLinked administrative data will be important to enable longitudinal studies of exceptionally large populations to explore asthma exacerbation, baseline and spikes of air pollution and risk factors. Analyses should control for type of educational assessment and specific particulate exposure. Studies should examine temporal changes and a variety of geographical settings to identify even weak associations to inform approaches to address inequalities of public health and education.
