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
Introduction: Human amniotic epithelial cell-derived extracellular vesicles (hAEC-EVs) have shown therapeutic potential in corneal injury repair; however, the underlying molecular mechanisms, particularly those related to extracellular matrix (ECM) remodeling, remain incompletely understood. Methods: A proteomic and bioinformatic strategy was applied to analyze ECM-related molecular alterations in corneal tissues following alkali injury and hAEC-EV treatment. Differentially expressed ECM-related genes were identified and subjected to pathway enrichment, protein-protein interaction, and immune infiltration analyses. To enhance experimental rigor, key findings were validated at both the transcript and protein levels using quantitative real-time PCR and Western blotting. In addition, Results: hAEC-EV treatment significantly upregulated ECM-stabilizing molecules, including A2M, LAMA1, and VIT, while downregulating the injury- and inflammation-associated protease CTSB at both mRNA and protein levels. Enrichment analyses revealed that hAEC-EVs modulate ECM-receptor interaction pathways and cell-ECM communication. Functional assays confirmed that hAEC-EVs directly enhance the proliferation and migration of human corneal epithelial cells and human corneal stromal cells. Immune infiltration analysis further suggested that hAEC-EVs reshape the corneal immune microenvironment toward a repair-permissive state. Conclusion: Through integrated proteomic, bioinformatic, protein-level validation, and functional analyses, this study demonstrates that hAEC-EVs promote corneal repair by coordinating ECM remodeling, regulating key signaling networks, and modulating immune responses, providing mechanistic support for their therapeutic application in corneal injuries.
