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
backgroundEMILIN-1 is an extracellular matrix glycoprotein with tumor-suppressive functions. While its loss is implicated in cancer progression, its specific role in the gastric tumor microenvironment and its clinical relevance remain poorly defined.
methodsUsing in vitro cellular systems and genetically modified mouse models we investigated the consequences of impaired EMILIN-1 function on gastric epithelial transformation, stromal remodeling, and fibroblast reprogramming. Histopathological analysis, gene expression profiling, and functional assays were employed to assess phenotypic changes in epithelial, fibroblastic, and endothelial compartments.
resultsWe found that gastric cancer (GC) cells downregulate EMILIN-1 in stromal fibroblasts and lymphatic endothelial cells via paracrine signaling, leading to reduced EMILIN-1 deposition and disrupted lymphatic organization. Mechanistically, the interaction between EMILIN-1 and α4β1 integrin, which is absent in GC cells, modulates tumor cell proliferation; loss of this axis allows tumor cells to escape ECM-mediated growth control. Furthermore, EMILIN-1 downregulation reprograms fibroblasts into a pro-tumorigenic phenotype, which enhances GC cell migration and clonogenic potential. EMILIN-1 loss-of-function (E955A) mice showed increased susceptibility to pre-neoplastic lesions, a finding mirrored in human dysplastic tissues where EMILIN-1 was markedly reduced.
conclusionOur findings establish EMILIN-1 as a master regulator of gastric tissue integrity. Its loss creates a tumor-permissive microenvironment by disrupting epithelial homeostasis, impairing lymphatic structure, and promoting fibroblast activation. The consistent reduction of EMILIN-1 in early human dysplasia highlights its potential as a novel stromal biomarker for early GC risk stratification. Moreover, restoring the EMILIN-1/integrin axis represents a promising therapeutic strategy to re-establish growth control and suppress tumor progression.
