Trends and Behavioral Correlates of Excessive Screen Time Among Swedish Adolescents: A Repeated Cross-Sectional Study (2017-2023).

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
Aim: This repeated cross-sectional study examined trends and behavioral correlates of excessive screen time among Swedish adolescents across 2017, 2020 and 2023. Specifically, this study examined 1) temporal trends of variables used, 2) correlates of pooled screen time, and 3) correlates of specific screen modalities (gaming, social media, and film/TV viewing). Methods: Data were collected from n=8,300 upper secondary school students in Jönköping County (n=2,319 in 2017; n=3,056 in 2020; n=2,925 in 2023). Measures used included risk behaviors (e.g., alcohol, smoking), physical activity, psychosocial trust, exposure to violence and victimization, sleep duration, psychosomatic symptoms, absenteeism and living arrangement. General linear models (GLM; UNIANOVA) were conducted, adjusting for relevant covariates. Results: Alcohol use, smoking, shorter sleep duration, higher psychosomatic symptoms, and school absenteeism were associated with higher pooled screen time, whereas physical activity, female gender, and living with both parents were associated with lower pooled screen time. Across modality-specific analyses, shorter sleep duration, lower physical activity, living without both parents, and school absenteeism were consistently associated with higher screen use across gaming, social media, and film/TV viewing, while substance-use and gender associations varied by modality. Conclusion: Sleep, physical activity, family structure, and school absenteeism appear to be robust correlates across screen modalities, supporting the importance of targeting these factors in adolescent health promotion and digital media guidance. These findings highlight the need for parents, researchers, and health professionals to pay closer attention to adolescents' digital media use.
