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
Objective: To explore the correlation between the type and duration of moderate-to- vigorous physical activity (MVPA) and mobile phone dependence among adolescents, so as to provide a scientific basis for intervention strategies for mobile phone dependence. Methods: A total of 971 eighth-grade junior high school students in Dalian were selected by mixed sampling. The Chinese version of the Children's Leisure Activities Study Survey was used to measure the type and duration of MVPA, and the Adolescent Mobile Phone Dependence Scale was used to assess the level of mobile phone dependence. Data were analyzed using independent samples Results: Open-skill MVPA was significantly negatively correlated with physical and mental impacts caused by mobile phone dependence ( Conclusion: Simply meeting the daily recommended duration of MVPA fails to alleviate adolescents' mobile phone withdrawal symptoms; only combining sufficient MVPA duration with open-skill PA yields a protective effect against mobile phone dependence. The findings of this study can provide a reference for PA arrangements in primary and secondary schools. It is recommended to promote open-skill PA and ensure that students meet the daily recommended duration of MVPA. Nevertheless, all data in this study were collected via self-reported questionnaires. Future research may integrate objective monitoring tools to further verify the findings of the present study.
