Global prevalence of myopia in children using digital devices: a systematic review and meta-analysis.
Synthesis in BMC pediatrics, 2025. 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
backgroundThe global prevalence of myopia among children has considerably increased over the past few decades, affecting the children's eye health and quality of life. According to the inconsistent reports of myopia among children, the purpose of this systematic review and meta-analysis study was to determine the global prevalence of myopia in children using digital devices.
methodsVarious databases (PubMed, ScienceDirect, Embase, Web of Science, Scopus, and Google Scholar) were searched systematically (No time limit until September 2023, last updated in May 2024) using keywords of "Myopia Prevalence", "Children", "TV", "Computer", "Video games", and "Smartphone". PRISMA guideline was also used for paper collection based on the Inclusion/Exclusion criteria. The quality of articles was determined based on the STROBE checklist. Data analysis, heterogeneity assessment, publication bias, and all factors influencing heterogeneity were executed using the CMA software (v.2).
resultsInitially, 828 articles were identified through database assessment. 563 and 133 papers were evaluated using primary and secondary assessments, respectively. Ultimately, 17 eligible articles were selected for meta-analysis following paper exclusion. In this era, the global prevalence of myopia among children using computer and video games was reported 28.8% (95%CI:21.1-38), using TV (TV watching) was 35.4% (95%CI:20.6-53.7), and smartphone usage was 31.4% (95%CI:13.5-57.3).
conclusionMyopia is now recognized as a critical global issue with a daily increasing rate. Technology, along with various digital devices, causes several issues in this era. It is suggested that the application of all digital screens and smart devices can potentially increase the risk of myopia among children. Thus, the reduction of these smart device applications in children can alleviate the potential risk of myopia. The results of this study can be a guide for health policymakers and a useful advertisement for society and families in paying attention to this problem in children, as well as increasing health interventions such as early screening and timely diagnosis for treatment. In this regard, it can be effective in both prevention and increasing the quality of life of children.
