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
backgroundLong non-coding RNAs have drawn increasing research interest in cancer biology. This study aims to investigate the function roles and the underlying mechanism of HnRNPU-AS1 in Hepatocellular carcinoma (HCC).
methodsqRT-PCR was performed to detect the expression levels of HnRNPU-AS1, miR-556-3p, miR-580-3p in HCC tissues and cell lines. Western blot was used to determine protein levels of LC3-II, LC3-I, Beclin-1, P62, and SOCS6. Functional assays including CCK8 assay, colony formation assay, wound healing assay, Transwell assay were performed to evaluate the role of HnRNPU-AS1 in regulating the malignant phenotype of HCC cells. Dual luciferase reporter assay and RNA pull-down experiment were used to examined the RNA-RNA interaction.
resultsHnRNPU-AS1 expression was decreased in HCC tissues and cell lines, which was associated with poor prognosis in HCC patients. Overexpression of HnRNPU-AS1 could inhibit the proliferation, migration, invasion but promote autophagy in HCC cells. Two miRNAs (miR-556-3p and miR-580-3p) were identified as potential targets of HnRNPU-AS1 in lncBASE database, which were significantly upregulated in HCC tissues and cell lines. Cell experiments demonstrated the effects of HnRNPU-AS1 overexpression could be attenuated by miR-556-3p or miR-580-3p overexpression. We further revealed that SOX6 was the downstream target of HnRNPU-AS1/miR-556-3p or miR-580-3p axis. Xenograft mouse model validated the tumor-suppressor role of HnRNPU-AS1 overexpression in vivo.
conclusionsThis study demonstrated the tumor suppressor function of HnRNPU-AS1 in HCC and identified the downstream molecules underlying its tumor suppressor function. Our results suggest that HnRNPU-AS1 suppresses HCC by targeting miR-556-3p and miR-580-3p/SOXS6 axis.
