The relationship between green space and myopia in children and adolescents: a systematic review and meta-analysis.

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: To investigate the effect of green space exposure on the risk of myopia in children and adolescents. Methods: Studies on the relationship between green space and myopia in children and adolescents published before October 1, 2024, were retrieved from five electronic databases: web of Science Core Collection, PubMed, EBSCOhost, ScienceDirect and Cochrane Library. A systematic review was conducted to summarize the relevant articles, followed by a meta-analysis. Results: A total of 11 studies were included in the systematic review, encompassing 2,224,332 participants aged 6-22 years. Of these, 6 studies were incorporated into the meta-analysis. Most studies indicated that increased green space is associated with a reduced risk of myopia. The Normalized Difference Vegetation Index (NDVI) showed a negative correlation with the prevalence of myopia in children and adolescents (cross-sectional studies: Conclusion: Increased exposure to green spaces has a beneficial effect on reducing the risk of myopia in children and adolescents. For every 0.1 increase in the NDVI, the prevalence of myopia decreases. Furthermore, the prevention and control of myopia are more effective within school boundaries and in the surrounding 500-meter buffer zone. Therefore, it is recommended that schools and relevant government authorities focus on enhancing vegetation coverage within school grounds and around areas where students frequently engage in activities, thereby providing stronger environmental support for myopia prevention in children and adolescents. However, potential publication bias cannot be excluded given the limited number of included studies; therefore, the pooled estimates should be interpreted with caution.
