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
backgroundColorectal adenocarcinoma (COAD) is a prevalent and lethal form of cancer. Understanding the molecular mechanisms underlying COAD progression is crucial for developing effective diagnostic and therapeutic strategies.
methodsThis study aims to explore wound healing-related genes in COAD and their potential roles in tumorigenesis and prognosis using
resultsA set of 70 genes associated with the "wound healing" term ere extracted from the Gene Ontology (GO) database (GO:0042060) and a protein-protein interaction (PPI) network was constructed using the STRING database. The PPI network was analyzed with the Cyto- Hubba plugin in Cytoscape, identifying four major hub genes: MMP2, FN1, NF1, and PTK7. We then analyzed the expression of these hub genes across 16 COAD cell lines and nine normal colon cell lines using RT-qPCR, finding significant overexpression in COAD cell lines. ROC curve analysis confirmed the diagnostic potential of these genes, with MMP2, FN1, and NF1 showing high AUC values. Expression validation using the TCGA COAD cohort, OncoDB, and HPA databases corroborated these findings, highlighting the overexpression and high protein levels of these genes in COAD. Promoter methylation analysis indicated lower methylation levels in COAD samples, suggesting dysregulation through epigenetic mechanisms. Genetic alteration analysis via cBioPortal revealed a spectrum of mutations, with FN1 being the most frequently mutated. Prognostic analysis using a KM plotter showed that high expression of the hub genes is associated with poorer overall survival (OS) and disease-free survival (DFS). Functional state correlations via CancerSEA suggested that these genes promote cell cycle, proliferation, metastasis, and stemness in COAD. Expression analysis in immune cells and drug sensitivity analyses highlighted the roles of MMP2, FN1, and NF1 in macrophages and drug resistance. A miRNA-mRNA network constructed using miRNet identified hsa-miR-200a-3p as a central regulator. Finally, functional assays in HCT116 cells demonstrated that knockdown of MMP2 and FN1 reduced proliferation, colony formation, and wound healing, suggesting these genes as potential therapeutic targets in COAD.
conclusionIn conclusion, our study identifies MMP2, FN1, NF1, and PTK7 as key wound healing-related hub genes in COAD.
