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
backgroundThe relationship between low social support at work and insomnia remains underexamined, especially regarding the mediating effect of job satisfaction. Our study focuses on unveiling how job satisfaction potentially shapes this association.
methodsData on paid workers were obtained from the 6th Korean Working Conditions Survey. The multivariable logistic regression models, stratified by sex, were conducted to estimate the crude and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for insomnia. An interaction and causal mediation analyses on insomnia were conducted between low social support at work and job satisfaction.
resultsAmong the 19,394 workers (9,046 male and 10,348 female), 1,490 (16.5%) male and 1,678 (16.2%) female had low social support at work and 524 (5.79%) of males and 867 (8.38%) of females experienced insomnia. The relationship between low social support at work and insomnia was significant in both sexes (adjusted OR [95% CI], male, 1.71 [1.39-2.12]; female, 1.34 [1.12-1.60]), respectively. In the interaction between social support at work and job satisfaction on insomnia, there were significant multivariable relationships. Additionally, 30.3% of the relationship between low social support at work and insomnia was mediated by job satisfaction in both sexes.
conclusionWe highlight the significant relationship between low social support at work and insomnia. Job satisfaction plays a crucial mediating role in this relationship.
