Association of shift work and shift patterns with thyroid function: A NHANES-based cross-sectional study.
Article in Medicine, 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
This cross-sectional study examined the association between shift work and thyroid function using data from the National Health and Nutrition Examination Survey 2007 to 2010. Weighted univariate and multivariate regression models were applied, with additional subgroup and interaction analyses performed. A total of 3578 participants were included (mean age 41.17 ± 13.31 years). After adjusting for potential confounders, shift workers exhibited significantly higher levels of thyroid-stimulating hormone (TSH) (β = 0.30; 95% CI: 0.14-0.45), thyroglobulin antibody (TgAb) (β = 11.62; 95% CI: 3.49-19.74), and thyroid peroxidase antibody (TPOAb) (β = 8.74; 95% CI: 1.07-16.40), alongside an increased prevalence of autoimmune thyroiditis (AIT) (OR = 1.69; 95% CI: 1.26-2.26) compared with day workers (all P < .05). Analyses stratified by shift type revealed that regular evening shifts were most strongly associated with elevated TSH (β = 0.58), subclinical hypothyroidism (SCH) (OR = 2.63), and AIT (OR = 2.29). Additionally, rotating shifts were specifically linked to higher TgAb levels and AIT risk. These findings indicate that shift work, particularly evening and rotating shift patterns, is associated with adverse thyroid-related outcomes.
