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
MicroRNAs (miRNAs) play important roles in carcinogenesis, but the global miRNA expression profile in gastric stromal tumor tissues remains unclear. This study was to examine the miRNA expression profile in gastric stromal tumor tissues and explore the function of dysregulated miRNAs by performing gene ontology (GO) and pathway enrichment analysis. Total RNA was extracted and purified from 3 pairs of frozen gastric stromal tumor tissues and the adjacent non-tumor tissues by using mirVana™ miRNA isolation kit. The miRNA expression was analyzed with Affymetrix microarrays (version 4.0) containing 2578 human mature microRNA probes. The dysregulated microRNAs were validated by quantitative RT-PCR in 30 pairs of gastric stromal tumor tissues. The target gene of the dysregulated microRNAs was predicted by miRanda, TargetScan and PicTar. GO and pathway enrichment analysis was conducted to examine the potential function of miR-3178 and miR-193a-5p. The results showed that there were 12 differently expressed microRNAs in gastric stromal tumor tissues, among which 10 miRNAs were down-regulated, and 2 were up-regulated (P<0.05). The validation results by RT-PCR were in accordance with those by microRNA microarry. GO analysis found that the target genes of miR-3178 were involved in 5 GO terms and those of miR-193a-5p in 7 GO terms in level 2. Pathway enrichment analysis suggested that miR-3178 and miR-193a-5p were related to 57 and 122 signaling pathways, respectively. It was concluded that gastric stromal tumor displays a unique miRNA signature. This specific expression may become a new diagnostic and prognostic biomarker for gastric stromal tumor. miR-3178 and miR-193a-5p function as suppressive microRNAs, and they may also become diagnosis and treatment targets for gastric stromal tumor.
