1 · What the graph read from it

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.

2 · The registry

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: In recent years, with the acceleration of the pace of modern life and the increase of life pressure, the prevalence of poor sleep quality has risen substantially among young people. Insufficient sleep and insomnia have emerged as a serious public issue in modern society. This study aimed to investigate the effect of perceived stress on sleep quality, with particular focus on the mediating roles of anxiety and sleep procrastination in the stress-sleep quality relationship. Methods: A total of 2,486 Chinese graduate students participated in the questionnaire survey, which used the Perceived Stress Scale, the Bedtime Procrastination Scale, the Pittsburgh sleep quality index, and the Self-rating Anxiety Scale. Descriptive statistics, correlation analysis, and the bootstrap method were utilized for data analysis. Results: The findings revealed a 37.8% prevalence of sleep disturbances among the participants. Notably, the mediating effects of anxiety and sleep procrastination in the association between perceived stress and sleep quality were statistically significant ( Conclusion: The results showed that higher perceived stress was positively associated with greater anxiety, which further contributed to sleep procrastination, and ultimately correlated with poorer sleep quality.
