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
Acute myocardial infarction (AMI) is the most important cause of death among cardiovascular diseases. Long noncoding RNAs (lncRNAs) have been widely implicated in the regulation of AMI progression. Discrimination antagonizing nonprotein coding RNA (DANCR) alleviated hypoxia-caused cardiomyocyte damages, and the underlying mechanisms remain unclear. Here, we investigated the function and mechanism of DANCR in hypoxia-induced cardiomyocytes and AMI model by enzyme-linked immunosorbent assay, reactive oxygen species and adenosine triphosphate measurement, and mitochondrial activity determination. Additionally, luciferase reporter assay, immunoblotting, and qRT-PCR were performed to validate the interactions between DANCR/miR-509-5p and miR-509-5p/Kruppel-like factor 13 (KLF13). The role of DANCR was also verified in AMI model by overexpression. Our results showed that DANCR expression was significantly downregulated in hypoxia-induced cardiomyocytes or AMI model. Overexpression of DANCR significantly alleviated mitochondrial damages, reduced inflammation, and improved cardiac function in the AMI model. Furthermore, we demonstrated that miR-509-5p/KLF13 axis mediated the protective effect of DANCR. The current study highlighted the critical role of DANCR in alleviating AMI progression through targeting the miR-509-5p/KLF13 signaling axis, suggesting that DANCR may serve as a potential diagnostic marker or therapeutic target for AMI.
