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 adopts a specificity perspective of different dimensions of physical exercise to examine the relationships between exercise intensity, duration, and frequency and smartphone addiction among college students, as well as the underlying psychological mechanisms. It further investigates the mediating roles of mindfulness and anxiety, with particular attention to the differences in how these exercise dimensions operate within the model. Methods: Using stratified random sampling, 1,795 college students in Fuzhou, Fujian Province, China, were surveyed. Physical exercise intensity, duration, and frequency were measured using the Physical Activity Rating Scale-3 (PARS-3), while mindfulness, anxiety, and smartphone addiction were assessed using the Mindful Attention Awareness Scale (MAAS), the Self-Rating Anxiety Scale (SAS), and the Smartphone Addiction Scale-Short Version (SAS-SV), respectively. Results: (1) All three dimensions of physical exercise-intensity, duration, and frequency-significantly and negatively predicted smartphone addiction (total effects: intensity = -0.139, duration = -0.119, frequency = -0.096; all Conclusion: Different dimensions of physical exercise show distinct associations with smartphone addiction among college students. By examining exercise intensity, duration, and frequency separately rather than treating physical activity as a single activity-level indicator, this study provides a new perspective for understanding the psychological mechanisms linking physical exercise and smartphone addiction.
