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
Gliomas are the most common tumors of the central nervous system, with glioblastoma (GBM) being particularly aggressive and fatal. Current treatments for GBM, including surgery and chemotherapy, are limited by tumor aggressiveness and the blood-brain barrier. Therefore, understanding the molecular mechanisms driving GBM growth is essential. Mitochondria, key players in cellular energy production, have been implicated in cancer development. In this study, we investigated the expression of mitochondrial transcription elongation factor (TEFM) in gliomas and its potential role in tumor progression. Analysis of data from The Cancer Genome Atlas (TCGA) revealed that TEFM transcript levels were significantly higher in glioma tissues compared to adjacent normal tissues. High TEFM expression was associated with poor survival outcomes in glioma patients. Furthermore, TEFM was notably upregulated in glioma tissue and in primary glioma cells derived from local patients, while its expression was relatively low in normal tissues and astrocytes. Silencing or knockout of TEFM significantly inhibited glioma cell growth, proliferation, clonogenicity, migration, and invasion, while inducing apoptosis and activating caspases. In contrast, ectopic overexpression of TEFM promoted tumorigenic activity, enhancing the malignant behavior of glioma cells. Co-expression analysis identified a strong correlation between TEFM and the epithelial-mesenchymal transition (EMT) pathway in gliomas. Notably, the expression of EMT markers, such as N-cadherin and Vimentin, decreased upon TEFM knockdown or knockout. Additionally, TEFM depletion impaired mitochondrial function, disrupting the mitochondrial respiratory chain in glioma cells. In vivo experiments demonstrated that TEFM knockout effectively suppressed the growth of subcutaneous glioma xenografts in nude mice. Collectively, these findings highlight the critical role of TEFM in GBM growth and invasion, suggesting that it could serve as a promising therapeutic target for glioma treatment.
