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
backgroundEpithelial-mesenchymal Transition (EMT) is involved in various cancers including glioblastoma. Our previous study has shown that miR-340 negatively correlated with EMT process in glioblastoma. PURPOSE: In the present study, we aim to explore the underlying molecular mechanisms of miR-340 in EMT process of glioblastomas. MATERIALS AND
methodsUsing RT-qPCR assay, we analyzed the expression of miR-340 in glioma cell lines and normal human glia (NHA) cell line. Using CCK8, Colony formation assays, transwell and Western blot assays, we investigated tumor growth and EMT process. Using luciferase reporter assay, we confirmed a target of miR-340.
resultsOur results showed that miR-340 was down-regulated in glioma cell lines (U87, U251 and LN229) compared to NHA cells. MiR-340 overexpression remarkably inhibited cell proliferation and invasion as well as up-regulated E-cadherin expression and down-regulated N-cadherin, Vimentin, ZEB1, Slug and Snail expressions in U251 and LN229 cells. Further studies have confirmed c-MET as a target gene of miR-340. The EMT-inhibitory effect of miR-340 was lost after c-MET expression was restored. We also identified the antitumorigenic activity of miR-340 in vivo.
conclusionThese results demonstrated that miR-340 functioned as a tumor suppressor via targeting EMT process and could be a potential therapeutic candidate for treating glioblastomas.
