Long-term exposure to low concentrations of ambient benzene with incident thyroid dysfunction and the mediating role of accelerated biological aging.
Article in Frontiers in public health, 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
Background: The associations between ambient benzene exposure and thyroid dysfunction (hypothyroidism and hyperthyroidism), as well as the role of biological aging, remain largely unknown. Methods: We included a total of 385,130 participants from the UK Biobank, and Cox regressions were used to assess the association between benzene exposure and incident thyroid dysfunction. We employed restricted cubic splines to fit potential nonlinear exposure-response relationships. Furthermore, interactions and mediation analyses were conducted to examine the mediating role of biological aging. Results: Benzene exposure was dose-responsively associated with an increased risk of thyroid dysfunction, each 1 μg/m Conclusion: Long-term exposure to low concentrations benzene may increase the risk of incident thyroid dysfunction. Accelerated biological aging demonstrated a significant additive interaction with benzene exposure on the risk of hypothyroidism and partially mediated the positive association between benzene exposure and the risk of hyperthyroidism.
