Impact of Marine Microplastics on Neurologic and Functional Disabilities: A Population-Level Study.
Article in European journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMicroplastics are emerging as environmental pollutants with potential neurotoxic effects, yet their association with neurological disabilities remains largely unexplored.
methodsIn this cross-sectional study comprising 218 coastal counties in the United States, we compared the self-reported prevalence of cognitive disability, mobility disability, self-care disability, and independent living disability in counties with very high and low marine microplastic levels (MMLs). Unadjusted and adjusted prevalence ratios (PRs) were computed using population-weighted quasi-Poisson regression across three different models to examine the relationship between disability prevalence and MMLs.
resultsCounties exposed to very high marine microplastic levels had a higher mean prevalence of self-reported cognitive disability (15.2% vs. 13.9%), mobility disability (14.1% vs. 12.3%), self-care disability (4.2% vs. 3.6%), and independent living disability (8.5% vs. 7.7%) compared to those exposed to low levels (p < 0.001). Regression analyses revealed significantly elevated adjusted prevalence ratios (PRs) for cognitive (PR: 1.09 [95% CI: 1.06-1.12], p < 0.001), mobility (PR: 1.06 [1.03-1.10], p < 0.001), self-care (PR: 1.16 [1.11-1.20], p < 0.001), and independent living disability (PR: 1.08 [1.05-1.12], p < 0.001) in counties with very high microplastic exposure compared to those with low exposure.
conclusionsThis study highlights a significant association between marine microplastic pollution and the self-reported prevalence of cognitive, mobility, self-care, and independent living disabilities at the county level. While merely associative, these findings emphasize the urgent need for further investigation into the individual-level health impacts of microplastic exposure and underscore the importance of environmental interventions to mitigate potential risks.
