Overexpression of TELO2 decreases survival in human high-grade gliomas.
Article in Oncotarget, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
High-grade gliomas are characterized with poor prognosis. To improve the clinical outcome, biomarker is urgently needed for distinguishing oncotarget in high-grade gliomas. Telomere maintenance 2 (TELO2) regulates S-phase checkpoint in cell cycle, and is involved in DNA repair. However, the role of TELO2 in survival outcome of high-grade gliomas is still not yet clarified. This study aims to investigate the correlation between TELO2 mRNA expression and survival outcome of patients with high-grade gliomas. Based on bioinformatics study, we found that Kaplan-Meier analysis demonstrated shorter survival in patients with higher TELO2 mRNA levels than in those with lower TELO2 expression (median survival, 59 vs. 113 weeks, p=0.0017, by log-rank test, hazard ratio: 0.3505, 95% CI: 01824.-0.6735). TELO2 mRNA expression significantly higher in World Health Organization (WHO) grade IV than in non-tumor control (p=2.85 x 10-9). Moreover, TELO2 level was greater in WHO grade III than in non-tumor controls (p= 0.017) human gliomas. We further validated TELO2 mRNA expression and protein levels by using quantitative RT-PCR, Western blot, and immunohistochemical (IHC) stain of tissue microarray. Consistently, the TELO2 mRNA and protein expression were significantly elevated in human glioma cells in comparison with normal brain control. Additionally, IHC staining showed higher TELO2 immunostain score in high-grade gliomas than in low-grade gliomas, or normal brain control. Taken together, human high-grade gliomas increase TELO2 mRNA expression, and overexpression of TELO2 mRNA expression correlates with shorter survival outcome, supporting that TELO2 is an oncotarget in human gliomas.
