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

Purpose: The development and progression of myopia are influenced by the Wnt7b/β-catenin signaling pathway. This study investigated the specific impacts of this pathway on the biomechanical properties of the sclera by altering the expression of matrix metalloproteinase-2 (MMP-2) to regulate type I collagen (collagen I) levels. Methods: We examined the effects of the Wnt7b/β-catenin signaling pathway and MMP-2 on human fetal scleral fibroblasts (HFSFs) and the sclera of guinea pigs with form-deprivation myopia (FDM). To explore the effects of the Wnt7b/β-catenin pathway and the role of MMP-2 in this context, we treated HFSFs and guinea pig sclera with specific agonists and inhibitors targeting Wnt7b/β-catenin and MMP-2. The expression levels of Wnt7b, MMP-2, and collagen I were subsequently analyzed quantitatively via western blot (WB) analysis, immunofluorescence, and quantitative real-time PCR (qRT-PCR) to assess protein and mRNA changes in response to pathway manipulation. Atomic force microscopy (AFM) was used to measure the elastic modulus of the treated HFSFs and guinea pig sclera to directly evaluate changes in cell and tissue stiffness. In the FDM model, essential ocular parameters such as refractive error and axial length (AL) were also assessed. Results: In vivo and in vitro activation of the Wnt7b/β-catenin signaling pathway significantly upregulated MMP-2 expression, which was accompanied by a notable decrease in collagen I levels. This change led to a reduction in the elastic modulus of both HFSFs and the sclera of guinea pigs with FDM. These significant biomechanical changes in the scleral tissue were indicated by a reduction in stiffness. Alterations in scleral biomechanics were associated with changes in ocular parameters, including an increase in AL and a myopic shift in refraction. Conclusions: The Wnt7b/β-catenin pathway regulates scleral biomechanics by upregulating MMP-2 expression, which leads to increased collagen I degradation and, consequently, an increase in axial elongation and a myopic shift in refractive error.
