1 · What the graph read from it

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.

2 · The registry

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: As digital life prevails among older adults, this study investigates how mobile social media functions affect their exercise identity and social-media-specific sedentary time. Methods: Using the S-O-R framework, a dual-path model was tested with SEM (AMOS 20.0) on data from 452 older adults in China. Results: Overall, mobile social media functions were not significantly associated with exercise identity or social-media-specific sedentary time. However, specific functions showed divergent effects: information retrieval ( Conclusion: Mobile social media exerts dual effects on older adults' exercise identity. Video media and personalized algorithms are key risk factors for social-media-specific sedentary time, while perceived value and immersive experience mediate distinct pathways.
