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
backgroundTo investigate the effect of miR-10a on renal tissues with ischemia reperfusion (I/R) injury in rats and to explore the underlying mechanisms of the effect of miR-10a on hypoxia-reoxygenation in HK-2 cells.
methodsMiR-10a level was measured in the renal tissues of rats with I/R rats using RT-PCR. In order to research the role of miR-10a in renal tissues, an miR-10 agonist and an miR-10a antagonist were used to treat I/R-injured rats. Levels of serum creatinine and blood urea nitrogen, renal histopathology, and levels of cell apoptosis were analyzed separately in renal tissues from the rats. Phosphatidylinositol 3-kinase (PI3K)/Akt pathway related proteins were measured by Western blotting. In addition, HK-2 cells were cultured in order to study the mechanism of action of miR-10a in the hypoxia-reoxygenation model being studied. Finally, the dual luciferase reporter gene assay was used to confirm that the PI3K p100 catalytic subunit α (PIK3CA) gene was targeted by miR-10a.
resultsAfter renal I/R injury in rats, miR-10a expression increased significantly (p < 0.05). Injection of miR-10a agonist significantly aggravated the renal injury and raised the level of cell apoptosis in the renal tissues of I/R-injured rats (p < 0.05). However, administration of miR-10a antagonist led to obvious improvement of the renal injury, decreased renal cell apoptosis, and inhibited PI3K/Akt pathway activity (p < 0.05). In in vitro experiments, the negative relationship between PIK3CA and miR-10a levels was confirmed. Furthermore, overexpression of miR-10a significantly decreased the proliferation of HK-2 cells, and increased cell apoptosis via up-regulation of the PI3K/Akt pathway (p < 0.05).
conclusionThe aggravation of renal I/R injury by miR-10a was associated with a decrease in the activity of PIK3CA/PI3K/Akt pathway.
