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
backgroundCerebral ischemia/reperfusion injury (CIRI) has complex pathogenesis, and inhibiting apoptosis and supporting neural progenitor proliferation are extremely beneficial strategies for treating CIRI. Unc-51-like kinase 4 (ULK4), a susceptibility gene for schizophrenia, promotes neural progenitors proliferation. The phosphatidylinositol 3-kinase (PI3K) pathway plays a critical role in CIRI via inhibition of apoptosis. Therefore, the relationship among ULK4, the PI3K pathway, and apoptosis in the context of CIRI has attracted our great interest. METHODS AND
resultsPrimary cortical neurons were subjected to oxygen-glucose deprivation/reperfusion (OGD/R), and rats were subjected to middle cerebral artery occlusion/reperfusion (MCAO/R). Transfection of the ULK4-overexpression lentivirus was performed alone or in combination with PI3K inhibitor treatment. Here, we revealed that ULK4 was poorly expressed in the cortex in MCAO/R rats and OGD/R-treated primary cortical neurons, ULK4 overexpression inhibited apoptosis, and reduced neurological deficit scores, cerebral infarct volume, and histopathological damage. Moreover, ULK4 overexpression increased PI3K expression and the p-protein kinase B/AKT and p-glycogen synthase kinase 3 beta (GSK3β)/GSK3β ratios, and inhibited apoptosis, while a PI3K inhibitor reversed the effects of ULK4 overexpression on CIRI.
conclusionsULK4 protects against CIRI, and the underlying mechanism involves PI3K pathway activation which in turn inhibits apoptosis.
