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
Background: This study aimed to identify 24-h movement behavior profiles on weekdays (WDs) and weekends (WEs) among primary and secondary school students in China and investigate the associations of these profiles with mental health. Methods: The study recruited 400 primary school students (mean age: 9.4 ± 1.9 years; 47.8% girls) and 819 secondary school students (mean age: 14.9 ± 1.4 years; 52.0% girls). Accelerometers were used to measure 24-h movement behavior, including sedentary behavior (SB), light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), and sleep. Mental health included depressive symptoms, internalizing/externalizing problems, working memory, and inhibition control. Latent profile analysis was used to identify 24-h movement behavior profiles. Results: Three profiles were identified among primary school students: "consistently low SB/high MVPA/long sleep", "consistently high LPA", and "consistently high SB/low PA/short sleep". The "consistently low SB/high MVPA/long sleep" and "consistently high LPA" groups had significantly lower depression levels, fewer internalized problems, better working memory, and better inhibition control than the other profiles. In secondary school students, "low MVPA (WDs) and low MVPA/high LPA (WEs)", "consistently high SB/low LPA/short sleep", "low SB/High LPA (WDs) and low SB/long sleep (WEs)", and "high MVPA/long sleep (WDs) and high MVPA (WEs)" were identified. The "high MVPA/long sleep (WDs) and high MVPA (WEs)" group had significantly lower depression levels and fewer internalized problems than the "consistently high SB/low LPA/short sleep" group. Conclusion: The study highlights the importance of promoting healthy 24-h movement behavior patterns. Mental health promotion strategies should aim to optimize 24-h movement behaviors (i.e., increasing MVPA, decreasing SB, and ensuring adequate sleep duration) or maintain high levels of LPA for primary school students. For secondary school students, they should focus on prioritizing ensuring adequate sleep and encouraging regular participation in MVPA.
