Association between work stress and sleep disturbances: the mediating role of pre-sleep arousal symptoms.
Article in Industrial health, 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
This study investigated the association between work stress and sleep disturbance among Korean workers, focusing on the mediating effects of somatic and cognitive pre-sleep arousal symptoms. Data were derived from the "Korean Work, Sleep, and Health Study (KWSHS)", involving 4,393 participants. Work stress was assessed using the Korean Occupational Stress Scale, and sleep disturbances were measured using the Insomnia Severity Index and Pittsburgh Sleep Quality Index. The Pre-Sleep Arousal Scale was utilized for assessing pre-sleep arousal status. For statistical analyses, the chi-square test, logistic regression analysis, and mediation analysis were used. Mediation analysis revealed that somatic pre-sleep arousal predominantly mediated the relationship between hazardous physical environments and insomnia symptoms (52.5%), while cognitive pre-sleep arousal was the primary mediator for high job demands (48.0%), organizational injustice (48.6%), and job insecurity (46.6%). These findings suggest that somatic and cognitive pre-sleep arousal serve distinct mediating roles in the relationship between specific types of work stress and sleep disturbances.
