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: Occupational radiation exposure poses unique health challenges, with emerging evidence suggesting links between chronic low-dose exposure, multisystem morbidity, and sleep disturbances. This study examines the relationship between cumulative morbidity burden and the risk of sleep disorders among radiation-exposed workers in southern China. Methods: A cross-sectional investigation was conducted from January to December 2024 at Guangzhou Twelfth People's Hospital. Morbidity burden was assessed through physician-diagnosed conditions classified by ICD-10 codes across seven disease categories. Sleep disorders were identified via a study-specific questionnaire. Multivariable logistic regression models, adjusted for demographic, occupational, and lifestyle confounders, were used to quantify associations between morbidity and sleep disorders. Subgroup analyses evaluated effect modification by sex, service duration, and profession. Results: A consecutive sample of 1,089 radiation workers underwent comprehensive health evaluations. Sleep disorders affected 33.0% of participants. A graded dose-response relationship was observed: workers with one morbidity exhibited 2.28-fold higher risk of sleep disorders (95%CI:1.68-3.10) compared to those without comorbidities. Risk increased to OR = 2.89 (1.97-4.25) for two morbidities and OR = 3.81 (2.42-6.01) for ≥3 morbidities after full adjustment. Subgroup analyses revealed significantly stronger associations in women (OR = 3.97, 1.94-8.42), workers with ≤15 years of service (OR = 4.24, 1.97-9.38), and biomedical engineers (OR = 5.75, 2.38-14.33). Thyroid, respiratory, cardiovascular, and lens opacity prevalence differed substantially between workers with sleep disorders and those without. Conclusion: Accumulating morbidity burden is robustly associated with sleep disorder risk among radiation workers, with occupational factors influencing the strength of this association. Biomedical engineers, women, and early-career personnel represent high-risk subgroups that warrant targeted screening and preventive interventions.
