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: This study examined the relationship between physical activity and short video addiction among college students, with a particular focus on the mediating roles of self-efficacy and loneliness. Methods: A cross-sectional survey was conducted among 581 students from three universities. Measures included validated scales assessing physical activity, self-efficacy, loneliness, and short video addiction, with demographic covariates (age, grade, major type [STEM vs. non-STEM], and urban-rural background). Data were analyzed using SPSS 27.0 and Hayes' PROCESS macro (Model 6). Bootstrap analysis (5,000 resamples) was employed to test mediation effects with 95% confidence intervals. Results: Physical activity was positively associated with self-efficacy and negatively associated with loneliness and short video addiction. Self-efficacy was negatively associated with both loneliness and short video addiction, whereas loneliness showed a positive association with short video addiction. Mediation analyses showed that physical activity reduced short video addiction both directly ( Conclusion: Physical activity reduces short video addiction directly and indirectly by enhancing self-efficacy and reducing loneliness, with a significant sequential mediation pathway. These findings highlight potential psychological mechanisms and provide practical implications for interventions targeting short video addiction among college students.
