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

Objective: This study aimed to analyze the impact of bedtime procrastination, rumination, loneliness, and positive body image on university students' sleep quality, and to explore potential mediating pathways and sex differences. Methods: A total of 674 students from a university in southern China were recruited. Assessments of participants' body measurements were conducted, followed by the completion of a general information questionnaire, Pittsburgh Sleep Quality Index, Bedtime Procrastination Scale, Body Appreciation Scale, Body Image-Acceptance and Action Questionnaire, Ruminative Responses Scale, and University of Loneliness Scale. Stepwise multiple linear regression and mediation models were employed to separately analyze the associations between sleep quality and the aforementioned factors in males and females. Results: Sex differences in sleep quality were apparent, with women having worse sleep quality than men ( Conclusions: Sleep quality and bedtime procrastination were worse in women than in men. The sleep quality of female students may be increased by focusing on enhancing positive body image, while for male students, managing rumination and reducing loneliness could be helpful.
