1 · What the graph read from it

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.

2 · The registry

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

Topic: This study systematically evaluates changes in retinal and choroidal microvasculature with increasing myopia severity. Clinical Relevance: Conflicting results in reported studies on the changes in retinal and choroidal microvasculature with increasing myopia severity require comprehensive analysis to guide patient management. Methods: The PubMed, Embase, and Web of Science databases were thoroughly searched for studies published before May 8, 2025 on retinal or choroidal changes across different myopia severities. Included were studies with cross-sectional or prospective case-control and cohort designs that reported outcomes of foveal avascular zone (FAZ) area and vessel densities (VD) in the retina and choroid. The risk of bias was assessed by the Newcastle-Ottawa Scale and the Agency for Healthcare Research and Quality tools. Funnel plot with Egger test assessed potential publication bias. Meta-regressions were conducted to identify potential moderators in subgroup meta-analyses with high heterogeneity. The protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO): CRD42023402550. Results: A total of 47 studies comprising 7293 eyes were included. Highly myopic eyes demonstrated significantly enlarged FAZ area in both the superficial capillary plexus (SCP) ( Conclusions: This meta-analysis revealed significantly enlarged FAZ areas and reduced VD in the macular and peripapillary regions with increasing myopia, especially in HM. These findings enhance the understanding of myopia-related fundus microvascular changes, guiding the clinical management and screening of patients with HM.
