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
backgroundMicroRNA host gene (MIRHG) lncRNA is a particular lncRNA subclass that can perform both typical and atypical lncRNA functions. The biological function of MIRHG lncRNA MIR194-2HG in cancer is poorly understood.
methodsLoss-of-function studies were performed in vivo and in vitro to reveal the biological function of MIR194-2HG in GC. MicroRNA PCR array, northern blotting, RNA sequencing, chromatin immunoprecipitation, and rescue assays were conducted to uncover the molecular mechanism of MIR194-2HG.
resultsIn this study, we reported an atypical lncRNA function of MIR194-2HG in GC. MIR194-2HG downregulation was clinically associated with malignant progression and poor prognosis in GC. Functional assays confirmed that MIR194-2HG knockdown significantly promoted GC proliferation and metastasis in vitro and in vivo. Mechanismically, MIR194-2HG was required for the biogenesis of miR-194 and miR-192, which were reported to be tumor-suppressor genes in GC. Moreover, hepatocyte nuclear factor HNF4A directly activated the transcription of MIR194-2HG and its derived miR-194 and miR-192. Meanwhile, BTF3L4 was proved to be a common target gene of miR-192 and miR-194. Rescue assay further confirmed that MIR194-2HG knockdown promotes GC progression through maintaining BTF3L4 overexpression in a miR-194/192-dependent manner.
conclusionThe dysregulated MIR194-2HG/BTF3L4 axis is responsible for GC progression. Targeting HNF4A to inhibit miR-192/194 expression may be a promising strategy for overcoming GC.
