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: Grade II/III gliomas are invasive brain tumors with a high risk of malignant progression and significant clinical heterogeneity, highlighting the urgent need for reliable prognostic biomarkers to guide personalized treatment strategies. This study aimed to investigate the molecular mechanisms driving glioma progression and to identify potential therapeutic targets. Methods: We analyzed 200 mitochondrial oxidative phosphorylation (OXPHOS)-related genes in 512 grade II/III glioma samples from The Cancer Genome Atlas (TCGA). Consensus clustering identified two distinct molecular subtypes (C1 and C2). Differentially expressed genes (DEGs) between subtypes were determined using the limma package. The immune cell composition and tumor microenvironment (TME) characteristics were assessed using ESTIMATE, MCPcounter, and CIBERSORT algorithms. Based on prognostic DEGs, we constructed a four-gene prognostic signature (MAOB, IGFBP2, SERPINA1, and LGR6). Results: The C2 molecular subtype was associated with poorer prognosis, higher immune scores, and enrichment in tumor-promoting pathways. The four-gene signature demonstrated strong prognostic performance and robustness across multiple independent validation cohorts. Immunohistochemical (IHC) analysis of clinical glioma specimens confirmed elevated protein expression levels of the four genes in tumor tissues. Discussion: Our OXPHOS-associated gene signature provides novel insights into the molecular classification, immune landscape, and prognosis of grade II/III gliomas. These findings lay the foundation for precision oncology and the development of targeted therapeutic interventions.
