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
Stroke, a type of acute cerebrovascular disease, is a global disease with high mortality. Neuronal ischemia and hypoxia are closely related to occurrence and development of cognitive impairment. Transmembrane p24 trafficking protein 10 (TMED10) as a transmembrane protein involves in vesicle protein transport in the secretory pathways. However, the function and mechanism of TMED10 on ischemic stroke and cognitive impairments remain unclear. In current study, TMED10 was highly expressed in cerebral ischemic penumbra of middle cerebral artery occlusion (MCAO) mouse model. Downregulation of TMED10 suppressed cell survival and facilitated apoptosis in primary cortical neurons, which were grown under oxygen glucose deprivation/reoxygenation (OGD/R) condition. Upregulation of TMED10 protected neurons form apoptosis induced by OGD/R. Further research indicated that the decrease of TMED10 resulted in neuronal mitochondrial injury through increasing reactive oxygen species (ROS) production. Meanwhile, TMED10 reduction induced neuronal apoptosis and mitochondrial damage through activating the c-Jun N-terminal kinase (JNK) pathway. Moreover, the knockdown of TMED10 increased cerebral infarction area, aggravated neuronal injury and promoted neuronal apoptosis through activating the JNK pathway in the cerebral ischemic penumbra of MCAO mouse model. Additionally, Morris water maze test verified that the severity of cognitive impairment increased with the decline of TMED10. Collectively, this study reveals that TMED10 inhibits mitochondrial damage, and protects neurons from apoptosis in MCAO-induced ischemic stroke and cognitive impairment via blocking the JNK pathway.
