Associations of Sleep, Screen Time, and Extracurricular Activities With Cognitive Development: A Longitudinal Study.
Article in Journal of adolescence, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionAdolescence is a sensitive period typified by marked cognitive and neural development, during which modifiable lifestyle factors may be particularly relevant. However, longitudinal associations of modifiable lifestyle factors-including sleep, screen time, and extracurricular activities-with cognitive development over time remain to be investigated, leaving the directionality of these relationships unclear.
methodsWe used baseline and 2-year follow-up data (n = 7043) from the Adolescent Brain Cognitive Development (ABCD) study. Linear mixed-effect models were employed to assess the association of modifiable lifestyle factors with the development of different cognitive functions over time. We additionally examined the moderating role of sex in these associations.
resultLonger sleep duration, greater time spent on nonphysical activities, and shorter duration of physical activity and screen usage-across passive watching, social media, and social engagement-were significantly associated with greater increases in cognitive scores. Sex moderated the association between passive screen watching and the duration of physical extracurricular activities with inhibitory control and attention. The negative association between passive watching and inhibitory control and attention development was stronger in females.
conclusionOur findings suggest that modifiable lifestyle factors are associated with adolescent cognitive development and point to the potential of lifestyle-based interventions to support optimal development during this formative period.
