Effect of Excessive Screen Time on Cardiorespiratory Fitness in Children: A Longitudinal Study.
Article in Children (Basel, Switzerland), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundThis study investigated the effect of different components of screen time (mobile phone use, TV/video viewing, and video gaming) on cardiorespiratory fitness (CRF) development in children aged 9-12 years.
methodsThis was a two-year longitudinal study conducted with 175 children (49.7% girls, mean age = 9.5) in Japan. CRF was assessed using a 20 m shuttle run test conducted at baseline and again at follow-up. Children were categorized as "Good" or "Poor" based on the change in CRF scores for each gender. Screen time was assessed using a self-reported questionnaire at baseline and termed as "high" if children reported ≥ 2 h/day. Univariate and multivariate logistic regression analyses were performed after adjusting for gender, physical activity, and time of data collection.
resultsChildren scoring "high" on mobile phone use had lower odds of being categorized as "Good" in CRF change (crude odds ratio (OR): 0.34; 95% confidence interval (CI): 0.15-0.90 (adjusted OR: 0.33; 95% CI: 0.12-0.91)). There were no significant effects of TV/video viewing (crude OR: 1.54; 95% CI: 0.84-2.81) and video gaming (crude OR: 0.98; 95% CI: 0.48-1.97) on changes in CRF.
conclusionsLimiting excessive mobile phone usage might be important for ensuring healthy development of CRF in children.
