Association between annual air pollutant exposure and thyroid function: a retrospective cross-sectional study.
Article in Journal of endocrinological investigation, 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
aimsDespite the high burden of air pollutants, the association between air pollutant exposures and thyroid function in the general population is inconclusive. This study aimed to investigate the association between annual exposure to air pollutants and thyroid function in Korean adults.
methodsThis cross-sectional study included a total of 16,193 participants (8,812 males, 7,381 females; mean age: 53.8 ± 13.1 years) who underwent health examinations at Seoul National University and had thyroid-stimulating hormone (TSH) concentrations within the range of 0.1-10.0 mIU/L. The yearly average levels of five air pollutants, including particulate matter (PM

conclusionsYearly exposure levels of air pollutants were positively associated with TSH, negatively associated with FT4 levels, and significantly associated with high TSH-low FT4. These findings suggest that exposure to ambient air pollution may contribute to thyroid function alterations at the population level, highlighting the importance of air quality improvement. Further longitudinal studies were warranted to consolidate these findings.
