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 aim of this study was to explore the neuroprotective effect and the underlying mechanism of erythropoietin (EPO) on the cortical neuronal cells insulted with oxygen and glucose deprivation (OGD). Different concentrations of EPO were used to determine the anti-apoptosis effect of EPO. In addition, PI3K inhibitor LY294002 and ERK1/2 inhibitor U0126 were added to explore the underlying mechanism of EPO. Cell apoptosis rate was measured by flow cytometry. The protein expression of Bax, Bcl-2, cleaved caspase-3, AKT, p-AKT, Erk1/2 and p-Erk1/2 wasmeasured by Western blot. Our results showed that EPO alleviates OGD-induced cell apoptosis in a dose-dependent manner; the neuroprotective effect of EPO was further confirmed by the fact that EPO treatment reversed the protein expression of cleaved caspase-3, as well as the Bcl-2/Bax ratio as compared with the OGD treatment. In the mechanism part, our results demonstrated that OGD and EPO nearly had no influence on the protein expression of AKT and Erk1/2 but altered the phosphorylation of them. Specifically, OGD decreased the expression of p-AKT and increased the expression of p-Erk1/2; while, EPO treatment reversed the expression of p-AKT and p-Erk1/2 as compared with OGD treatment. Interestingly, LY294002 decreased the expression of p-AKT and attenuated the neuroprotective effect of EPO; while, U0126 decreased the expression of p-Erk1/2 and enhanced the neuroprotective effect of EPO. Our study demonstrated that EPO protects neurons against apoptosis induced by OGD, which is closely related with activation of PI3K/AKT and inactivation of Erk1/2 signaling pathway.
