Occupation Associated with Altered Steroid Hormone Metabolism in Men: A Cross-Sectional Metabolome-Wide Association Study.
Article in Research square, 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
Objectives: This exploratory study aims to characterize metabolic distinctions among men in crafts and labor occupations hypothesized to underlie the shared risk of chronic diseases observed among occupational groups historically referred to as blue collar. Methods: Using high-resolution mass spectrometry, we characterized the serum metabolome of 220 men (n = 98 vs. 122, craftsmen and laborers vs. others) enrolled in the founding generation (1959-1967) of the Child Health and Development Studies. Metabolic changes associated with occupation were identified using Student's t-tests and multivariable linear regression models, followed by pathway enrichment analysis. Results: Alterations in steroid hormone metabolism were consistently found among craftsmen and laborers. The abundance of C21-steroids, such as tetrahydrocorticosterone, were increased in craftsmen and laborers, whereas C19-steroids, including androstenedione, testosterone, and 5-dihydrotestosterone, were reduced. Alteration of energy metabolism was also evidenced by reductions in acylcarnitines. In addition, several metabolic pathways such as androgen synthesis, carnitine shuttle, and bile acid synthesis showed BMI-dependent differences. Conclusion: Alterations in steroidogenesis and energy metabolism observed in serum samples from male craftsmen and laborers offer insights into the biological pathways that may contribute to increased health risks in both these workers and their offspring. These findings provide a framework for elucidating shared metabolic responses associated with a suite of occupational conditions characteristic of craftsmen and laborers.
