Association of daily screen time and sleep with concussion history on academic grades: a United States youth risk behavior survey study.
Article in Preventive medicine reports, 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
Objective: We evaluated the association between daily hours of sleep, daily hours of screen time, concussion history, and academic performance in a sample of adolescents. Study design: The United States Youth Risk Behavior Survey datasets from 2017 to 2021 were analyzed. The unweighted sample included 29,388 adolescents, representing an estimated 12,097,952 adolescents. We analyzed history within the last year of sport- or recreation-related concussion, daily television, video games, and computer usage (3+ hours/day on average), sleep (8+ hours of sleep/day), daily physical activity (60+ minutes/day on 5+ days/week), sport participation, and averaging "A" or "B" grades. Results: The moderation model (R Conclusion: Adolescents who reported a sport- or recreation-related concussion in the previous year and daily screen time 3+ hours per day or sleep <8 h per day had poorer academic performance than those who reported less screen time and reported more sleep.
