1 · What the graph read from it

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.

2 · The registry

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

Glioblastoma (GBM) is among the most aggressive primary brain tumors, with a median survival rate of 12-15 months. MicroRNAs have been implicated in GBM development as oncogenes or tumor suppressors. In this study, we demonstrated that miR-519a expression was frequently downregulated in GBM specimens and cell lines, and that low-levels miR-519a expression significantly correlated with poor outcomes associated with GBM. Analysis of The Cancer Genome Atlas also demonstrated that low miR-519a expression can predict poor clinical outcomes in classical and proneural GBM subtypes. Functionally, re-expression of miR-519a effectively reduced GBM cell proliferation, migration, and invasion. Mechanistically, we confirmed that the signal transducer and activator of transcription 3 (STAT3) 3'-UTR was a putative target of miR-519a, and that re-expression of STAT3 abrogated miR-519a function in GBM cells. Furthermore, we found that STAT3 expression negatively correlated with that of miR-519a in human GBM tissues. These results elucidated the prognostic value and tumor-suppressor role of miR-519a in GBM and further suggested it as a potential therapeutic target for GBM treatment.
