Physical activity and short-form video addiction among adolescents: the chain mediating role of cognitive flexibility and anxiety.
Article in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Short-form video platforms have become a common source of entertainment and social interaction among adolescents. Excessive or poorly controlled use may be associated with adverse psychological and behavioral outcomes. This study examined the association between physical activity and short-form video addiction and tested whether cognitive flexibility and anxiety statistically mediated this association. Methods: A cross-sectional study was conducted during the autumn term of 2023 via a convenience sampling method from three secondary institutions located in Hunan Province, China. The resultant sample comprised 492 adolescents (236 male, 256 female), with an average age of 15.36 years (SD = 0.54). Self-reported measures of physical activity, cognitive flexibility, anxiety, and short-form video addiction were collected and analyzed using a mediation model. Results: Physical activity was negatively correlated with short-form video addiction ( Conclusions: Higher physical activity was associated with lower short-form video addiction among the adolescents studied, and this association was partly explained by cognitive flexibility and anxiety. Because the study was cross-sectional, the findings should be interpreted as correlational evidence rather than proof of temporal or causal mechanisms.
