How Long Is Too Long? Effects of Mobile Game Duration on Stress and Cognitive Function by Gender.
Article in International journal of exercise science, 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
Mobile gaming is widely popular among young adults; however, its effects on stress and cognitive function across different play durations and genders remain unclear. This study examined the acute effects of mobile gaming session duration on heart rate (HR), stress, selective attention, and visual short-term memory (VSM) in male and female university students playing Realm of Valor (ROV), a popular multiplayer online battle arena game. Twenty recreational ROV players (10 males, 10 females; aged 20-22 years) completed a randomized crossover trial involving two remotely supervised gaming sessions: three games (~1 hour) and seven games (~3 hours), separated by a 7-day washout period. Participants played in consistent teams from their home environments. HR, stress (Suanprung Stress Test-20), selective attention (Stroop Color and Word Test), and VSM (CogniFit task) were assessed before and after each session using standardized, investigator-monitored protocols. HR increased significantly following both gaming sessions, with no difference between durations. Stress levels increased only after the seven-game session, with females exhibiting greater increases than males. Selective attention improved after three games but not after seven, with greater gains observed in the shorter session. VSM accuracy and response time did not differ significantly between gaming durations. These findings suggest that short-duration mobile gaming may enhance attentional performance with minimal stress, whereas prolonged play increases stress, particularly in females, and diminishes cognitive benefits.
