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

Depressive symptoms are a common mental health concern among adolescents, with prevalence steadily increasing and showing a trend toward younger age groups. This cross-sectional study aimed to examine the relationship between sleep procrastination and depressive symptoms among adolescents, with a particular focus on the mediating role of eating behavior. Stratified cluster sampling was used to select participants, who completed a battery of questionnaires, including the General Circumstances Investigation, Sleep Procrastination Scale (SPS), Patient Health Questionnaire-9 (PHQ-9), and Sakata Eating Behavior Scale Short Form. Logistic regression and restricted cubic spline models were employed to examine the relationship between sleep procrastination and depressive symptoms, and a mediation model was applied to analyze the indirect effect of eating behavior.The results indicated that sleep procrastination was positively associated with depressive symptoms, exhibiting a significant nonlinear association (p < 0.05). Mediation analysis revealed a significant indirect effect of sleep procrastination on depressive symptoms via eating behavior (β = 0.097, 95% CI [0.058, 0.143]), and this indirect association was not significantly moderated by sex. In conclusion, the indirect effect of sleep procrastination on depressive symptoms via eating behavior was statistically significant, consistent with a partial mediation model. These findings suggest that sleep procrastination is associated with depressive symptoms both directly and indirectly via eating behavior.
