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
The pathogenesis of ischemic stroke is extremely complex and has a significant impact on the quality of life of the patients. Accumulating studies have reported that long non-coding RNAs (lncRNAs) may be associated with the progression of ischemic stroke. However, the role and underlying mechanism of action of the lncRNA testis-specific transcript Y-linked 15 (TTTY15) in ischemic stroke remains unknown. The present study analyzed the expression levels of TTTY15 in PC12 cells injured by oxygen-glucose deprivation/reperfusion (OGD/R). The effects of the knockdown of TTTY15 expression on the levels of the inflammatory cytokines TNF-α, IL-1β, IL-18 and IL-10, cell apoptosis and the expression levels of the apoptosis-associated proteins Bcl-2, Bax, cleaved caspase-3, caspase-3, cleaved caspase-9 and caspase-9, were subsequently analyzed in OGD/R-treated PC12 cells using ELISA, flow cytometry and western blotting, respectively. In addition, the downstream target gene of TTTY15 was verified using a dual luciferase reporter assay. The effects of TTTY15 on the inflammation and apoptosis of PC12 cells treated with OGD/R were determined by targeting miR-766-5p. The results of the present study revealed that TTTY15 expression was upregulated in OGD/R-treated PC12 cells. The knockdown of TTTY15 significantly decreased the concentrations of the proinflammatory factors TNF-α, IL-1β and IL-18, while it increased the concentration of the anti-inflammatory cytokine IL-10 in OGD/R-treated PC12 cells. Apoptosis was also suppressed following gene silencing of TTTY15. Subsequently, miR-766-5p was identified as a target gene of TTTY15 using a dual luciferase reporter assay and the expression levels of TTTY15 and miR-766-5p were found to be negatively correlated. The overexpression of miR-766-5p alleviated the stimulatory effect of TTTY15 overexpression on the inflammation and apoptosis of PC12 cells treated with OGD/R. Therefore, the present study revealed that TTTY15 knockdown improved the OGD/R-induced injury of PC12 cells by upregulating miR-766-5p expression.
