Exercise modulates behavioral and neural mechanisms of working memory in excessive short video users.

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 associations between different exercise habits, working memory performance, and prefrontal cortical activation patterns in male college students with excessive short video use. Methods: Eighty-two male college students were recruited. Behavioral tests and functional near-infrared spectroscopy (fNIRS) were used to assess working memory performance and prefrontal oxygenated hemoglobin (OxyHb). Participants were classified by daily exercise habits (high exercise habits [HE], low exercise habits [LE], no exercise habits [NE]) and short video usage (low video [LV], moderate video [MV], high video [HV]). Results: (1) In working memory tasks, the LV group exhibited significantly shorter reaction times and higher accuracy ratio than the MV and HV groups (all Conclusion: Excessive short video use was associated with poorer working memory performance, whereas regular exercise habits were associated with better behavioral performance. Moreover, exercise habits and short video use interacted to modulate prefrontal OxyHb in regions critical for cognitive control and decision-making. These findings suggest that promoting regular physical exercise may help counteract the negative cognitive effects of excessive short video consumption.
