Downregulation of Microrna-421 Relieves Cerebral Ischemia/Reperfusion Injuries: Involvement of Anti-apoptotic and Antioxidant Activities.
Article in Neuromolecular medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
Reperfusion after cerebral ischemia causes additional ischemic injuries due to sudden recovery of blood supply. It usually produces excessive reactive species, mitochondrial dysfunction, oxidative stress, and cell apoptosis. Our study is designed to examine the role of miR-421 antagomir in cerebral ischemia/reperfusion injuries, as well as its underlying mechanisms. Middle cerebral artery occlusion (MCAO) model was performed with male Sprague Dawley (SD) rats for the initiation of cerebral ischemia/reperfusion injuries. Malondialdehyde (oxidative stress marker) and superoxide dismutase (antioxidant enzyme) were measured as indicators for oxidative stress. Flow cytometry was utilized to evaluate the cell apoptosis effects from miR-421. miR-421 antagomir significantly decreased neurological deficits and infarction volumes. It also downregulated malondialdehyde contents, upregulated superoxide dismutase activities, promoted the expressions of myeloid cells leukemia-1 and B cells lymphoma-2, and downregulated the expressions of Bax in the ischemic cortex. In addition, miR-421targeted MCL1 to exert its biological functions. Our study indicated the neuroprotection effects of miR-421 antagomir on cerebral I/R injuries, which involved the suppression of cell apoptosis and oxidative stress. MiR-421 might provide a new therapeutic direction for ischemia/reperfusion injuries.
