Association between ethylene oxide exposure and Klotho levels in US adults.
Article in Scientific reports, 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
Ethylene oxide (EO) is an industrial chemical used in the production of both consumer and non-consumer products.Additionally, it is utilized as a gaseous sterilant for medical devices. As an anti-aging hormone, kloth involved in various physiological processes. At present, the association between EO exposure and klotho remains uncertain. In this retrospective cross-sectional study, 1696 participants aged 40-79 years in the 2013-2016 National Health and Nutrition Examination Survey were included. EO exposure was measured using the hemoglobin adducts of EO (HbEO) in human whole blood or erythrocytes. Klotho levels were also measured in blood samples. Linear regression, smooth curve fitting, and subgroup analyses were used to assess whether HbEO was associated with klotho level. After full adjustment for confounders, the negative association between log2HbEO and klotho was observed after multivariate adjustment (β=-17.29, 95% CI = - 28.42 ~ - 6.17, P = 0.002). When EO was categorized into quintiles, the fifth quintile exhibited significant differences compared to the lowest quintile (β=-70.79, 95% CI = - 122.54 ~ - 19.04, P = 0.007). The curve fitting shows an inverse "L-shaped" relationship between log2HbEO and klotho (P for nonlinearity = 0.04). In summary, a negative and nonlinear relationship was found between log2HbEO and klotho. Further research is required to confirm the causality of this connection and clarify the underlying mechanisms.
