ReviewNeurotoxicology2026
A critical review of potential modifiers of air pollutant associations with dementia and related outcomes.
Review in Neurotoxicology, 2026. 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
backgroundAir pollution has been linked with poor cognitive and brain health, including Alzheimer's Disease and Related Dementia (ADRD). However, whether specific individuals are more susceptible than others remains unclear. PURPOSE: We aimed to review potential modifiers of the air pollution-cognitive/brain health association and identify subgroups potentially susceptible to adverse effects of air pollution exposure.
methodsWe identified published, peer-reviewed articles in the Embase and Medline databases through the Ovid and PubMed search platforms and used Covidence, an online software tool, to extract relevant data from eligible articles. We then systematically reviewed and summarized the evidence on how health behaviors, genetic/molecular factors, environmental factors, and individual factors modify the association between ambient air pollution and cognitive/brain health.
resultsSeventy-four publications, out of 6372 relevant publications, met the eligibility criteria and were included in this review. Available studies suggested that race/ethnicity, geographic location, apolipoprotein E (APOE) e4 allele, socioeconomic status (SES), body mass index (BMI), and diet may modify the air pollution-ADRD association, and that age and education do not, although the available evidence precludes firm conclusions. Limited reporting precludes conclusions about other modifiers.
conclusionEfforts to reduce the harmful effects of air pollution exposure should consider sensitive groups. The current literature suggests differential susceptibility to the adverse effects of air pollution on cognitive and brain health. Future studies should include standardized reporting of effect modification for the likely modifiers identified here, allowing for more robust conclusions.
