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
Emerging evidence suggests that circular RNAs (circRNAs) are involved in the regulation of tumourigenesis and progression of a variety of malignant tumours. In this study, we aimed to identify laryngeal squamous cell carcinoma (LSCC)-specific circRNAs and explore their biological functions and underlying molecular mechanisms. Employing microarray and qRT-PCR, hsa_circ_0000825 was found to be significantly increased in LSCC tissues versus para-cancerous tissues. High hsa_circ_0000825 expression was positively associated with advanced clinical stages, lymph node metastasis, and poor survival. Furthermore, the overexpression of hsa_circ_0000825 in TU177 and AMC-HN-8 cells promoted cell proliferation. Transwell assays showed enhanced migration and invasion of TU177 and AMC-HN-8 cells upon overexpression of hsa_circ_0000825. Conversely, the knockdown of hsa_circ_0000825 had the opposite effect. Xenograft tumours in BALB/c nude mice derived from hsa_circ_0000825-overexpressed TU177 cells showed greater volume and weight than those derived from control TU177 cells. Mechanistically, nuclear-cytoplasmic fractionation assay confirmed that hsa_circ_0000825 was mainly located in the cytoplasm of TU177 and AMC-HN-8 cells. The AGO2-RNA immunoprecipitation (RIP) assay revealed that hsa_circ_0000825 was significantly enriched in the AGO2-precipitated complex in both TU177 and AMC-HN-8 cells, suggesting that this circRNA may function via a competitive endogenous RNA (ceRNA) mechanism. Next, bioinformatics analysis, biotinylated-oligo pull-down assay and dual-luciferase reporter assay verified that miR-766 could be sponged by hsa_circ_0000825 and also target 3'UTR of HOXD10 mRNA. Moreover, miR-766 was shown to be involved in the pro-oncogenic effect of hsa_circ_0000825. This occurred via the mediation of hsa_circ_0000825-enhanced HOXD10 mRNA by the ceRNA mechanism in TU177 and AMC-HN-8 cells. Besides, RNA-binding protein (RBP) ELAVL1 interacted with hsa_circ_0000825 in TU177 and AMC-HN-8 cells, as revealed through bioinformatics analysis, biotinylated-oligo pull-down assays, and RIP assays. ELAVL1 knockdown decreased cell proliferation by 38 % and 34 % in hsa_circ_0000825-overexpressed TU177 and AMC-HN-8 cells (
