1 · What the graph read from it

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.

2 · The registry

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

aimsInflammatory processes induced by leukocytes are crucially involved in the pathophysiology of acute ischemic stroke. This study aimed to elucidate the inflammatory mechanism of long non-coding RNA (lncRNA) H19-mediated regulation of C1q and tumor necrosis factor 6 (C1QTNF6) by sponging miR-29b in leukocytes during ischemic stroke.

methodsH19 and miR-29b expression in leukocytes of patients with ischemic stroke and rats with middle cerebral artery occlusion were measured by real-time polymerase chain reaction. H19 siRNA and miR-29b antagomir were used to knock down H19 and miR-29b, respectively. We performed in vivo and in vitro experiments to determine the impact of H19 and miR-29b on C1QTNF6 expression in leukocytes after ischemic injury.

resultsH19 and C1QTNF6 upregulation, as well as miR-29b downregulation, was detected in leukocytes of patients with stroke. Moreover, miR-29b could bind C1QTNF6 mRNA and repress its expression, while H19 could sponge miR-29b to maintain C1QTNF6 expression. C1QTNF6 overexpression promoted the release of IL-1β and TNF-α in leukocytes, further exacerbated blood-brain barrier disruption, and aggravated the cerebral ischemic injury.

conclusionsOur findings confirm that H19 promotes leukocyte inflammation by targeting the miR-29b/C1QTNF6 axis in cerebral ischemic injury.
