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
backgroundAddictive screen use (ASU), above and beyond screen time, has been linked to significant mental health risks. Yet little is known about the neural risk factors that may associate with ASU. We examined 2 neurodevelopmental factors-cognitive control and reward-highlighted in substance use research and their links to ASU.
methodsWe utilized resting-state and monetary incentive delay (MID) task functional magnetic resonance imaging data from the Adolescent Brain Cognitive Development (ABCD) Study at baseline (Y0; ages 9-10 years) to predict addictive videogaming, addictive social media use, addictive phone use, and a composite measure of ASU at year 2 follow-up (Y2; ages 11-12 years). Cortical connectomic maturation was operationalized as distance from early life and proximity to adult functional networks in an individual connectome to potentially index cognitive control development. This was also supplemented by assessing cognitive task performance. Nucleus accumbens (NAc) activation in anticipation of reward in the MID task was used to assess reward processing.
resultsAbove and beyond total screen time and attention problems, lower connectomic maturation at Y0 associated with Y2 higher ASU composite and addictive videogaming. Analyses including task performance indicated that cortical maturation was associated with both ASU and task performance, but we did not find cognitive task performance to be directly related to ASU. Additionally, lower NAc anticipatory reward activation at Y0 was very weakly associated with higher Y2 ASU.
conclusionsDelayed cortical network maturation and, to a lesser extent, lower anticipatory reward activation in 9-to-10-year-old children may be associated with ASU in early adolescence, above and beyond parent-reported attention problems.
