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
Purpose: This secondary data analysis examined the relationship between sleep patterns (including bedtime and wake-up time), chronotype, and depressive symptoms in adolescents aged 13~18 years. Methods: Data were derived from the 19th Youth Risk Behavior Survey conducted in 2023. Of the 52,880 respondents, 5,893 were excluded, resulting in a final analytic sample of 46,987 adolescents. Complex sample logistic regression analyses were conducted using SAS version 9.4 to investigate the effects of sleep patterns and chronotype on depressive symptoms. Results: Among the 46,987 participants, 11,967 reported depressive symptoms, yielding an estimated prevalence of 25.3%. Statistically significant differences in bedtime, wake-up time, sleep duration, and chronotype were identified between adolescents with and without depressive symptoms ( Conclusion: This study demonstrated that sleep duration, sleep patterns, and chronotype are associated with depressive symptoms in adolescents. Interventions should target extending sleep duration through earlier bedtimes and encouraging a shift from evening-type to morning-type chronotypes, which may help alleviate depressive symptoms.
