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

Background: High myopia significantly increases the risk of serious ocular complications. The purpose of this study was to characterize ocular biometric variations across different degrees of myopia in young Saudi adults and to identify biometric parameters most strongly influenced by refractive severity. Methods: In this cross-sectional study, 163 eyes from individuals aged 18-31 years with myopia ranging from -1.00 to -11.00 D were evaluated at the university medical clinics. Anterior segment parameters such as white-to-white (WTW) corneal diameter, anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), and central corneal thickness (CCT) were measured using the Pentacam, axial length (AXL) was assessed with the IOL Master. Intraocular pressure (IOP) was measured with a non-contact tonometer. Finally, AXL, anterior chamber parameters, WTW, CCT and IOP were compared among the low, moderate, and high myopic groups. Results: Myopia severity showed a statistically significant positive correlation with AXL, WTW corneal diameter, ACD, ACV, CCT, and IOP ( Conclusion: Myopia severity in young adults is associated with significant structural changes, primarily AXL elongation and only minimal enlargement of anterior segment dimensions particularly the ACD and ACA, suggesting that posterior expansion predominates over anterior. These biometric patterns have important implications for refractive surgery planning, glaucoma risk assessment, and monitoring of myopia progression.
