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
purposeTo investigate the correlation between axial length (AL) and the elasticity of the posterior segment wall of the eyeball using shear wave elastography in myopic eyes without posterior staphyloma.
methodsThis cross-sectional study enrolled 87 right eyes, including 29 with high myopia (spherical equivalent ≤ -6.00 D) and 58 with low myopia (-6.00 D < spherical equivalent ≤ -0.50 D). The AL measured with Pentacam and the elasticity of the eyeball wall at different locations (including the macular region, near the optic nerve, and near the midperiphery) could be reflected using shear wave elastography. Multivariate regression analysis was used to explore the correlations between AL and elasticity at different locations.
resultsA significantly lower elasticity measurement was observed in high myopia group at the macular region, 3.5 mm from the nasal side of the optic nerve, temporal and nasal sides of the optic nerve, and temporal and nasal sides of the midperiphery in both horizontal and vertical directions (P < 0.01). Furthermore, the elasticities at the macular region in both horizontal and vertical directions had significant correlations with AL (P < 0.001).
conclusionThe elasticity of the eyewall at the macular area decreased with an increase in AL, which may explain why posterior scleral staphyloma is most likely to occur at the macular area. The macular area should be paid more attention in high myopia. These microstructural changes indicated by the difference in elasticity of the posterior segment wall maybe lead to the progression of posterior staphyloma.
