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
Background: Glioblastoma is a highly aggressive brain tumor, and the transition from the proneural to mesenchymal subtype is associated with more aggressive and therapy-resistant features. However, the signaling pathways and genes involved in this transition remain largely undefined. Methods: We utilized patient-derived xenograft (PDX) samples of glioblastoma, specifically PDX-L14, which exhibit both negative and overexpressed FOSL1 expression. mRNA expression profiles were assessed by RNA sequencing in these samples, followed by gene ontology (GO) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and Gene Set Enrichment Analysis (GSEA). Validation of the hub genes was performed using qPCR and immunohistochemistry assays. Results: Differentially expressed genes (DEGs) between FOSL1 overexpression groups were predominantly involved in ferroptosis, immune response, angiogenesis, vascular mimicry, autophagy, epithelial-mesenchymal transition (EMT), cancer cell stemness, temozolomide (TMZ) resistance, and NF-κB signaling. Downregulated DEGs were associated with TMZ resistance, glioma proliferation, RNA processing, and Wnt/β-catenin signaling. Key enrichment pathways, including NF-κB, Want, and BMP, are all critical for maintaining glioma stemness. FOSL1 was found to regulate RNA processing and ubiquitination. Notably, 8 upregulated (ITGA5, SDC1, PHLDB2, TNFRSF8, ADAM8, TLR7, STEAP3, and POU3F2) and 4 downregulated (IFIT1, FBXO16, ARL3, and BEX1) genes were identified, with implications for glioblastoma prognosis. Conclusion: This transcriptome investigation emphasizes the diverse functions of FOSL1 in different biological processes and signaling networks during the shift from proneural to mesenchymal state in glioblastoma.
