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
backgroundIschemic stroke (IS) is known for its high morbidity, disability and mortality rates, and studies designed to explore its pathophysiological mechanisms and identify novel therapeutic strategies are urgently needed. We aimed to probe the effects of the deubiquitinase OTUD3-IRP2-p53/PTGS2 pathway on cerebral ischemia‒reperfusion (I/R) injury and hippocampal neuron ferroptosis.
methodsA cerebral I/R mouse model was established. Furthermore, lentiviral vectors that overexpressed OTUD3 and knocked down IRP2 were constructed, and a series of assays were performed to probe the OTUD3/IRP2/p53/PTGS2 mechanism. An oxygen‒glucose deprivation and reoxygenation (OGD/R) model of mouse hippocampal neurons was constructed. Then, OTUD3 and IRP2 were knocked down and overexpressed, and p53 was overexpressed to explore the mechanism of the OTUD3/IRP2/p53/PTGS2 pathway.
resultsOTUD3 and IRP2 were expressed at low levels in cerebral I/R models. OTUD3 promoted IRP2 expression to protect damaged hippocampal neurons. Moreover, IRP2 affected ferroptosis in hippocampal neurons. In addition, IRP2 inhibited p53. After IRP2 and p53 were overexpressed, IRP2 regulated the p53/PTGS2 pathway and affected ferroptosis in hippocampal neurons. In vivo, after overexpressing OTUD3 and knocking down IRP2, we found that overexpression of OTUD3 promoted IRP2 expression to reduce ferroptosis in hippocampal neurons and improve cerebral I/R injury via the inhibition of the p53/PTGS2 pathway.
conclusionsThe deubiquitinase OTUD3 stabilized IRP2 expression to reduce hippocampal neuron ferroptosis via the p53/PTGS2 pathway to subsequently ameliorate cerebral I/R injury.
