The circular RNA
Article in Neural regeneration research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Circular RNAs can regulate the development and progression of ischemic cerebral disease. However, it remains unclear whether they play a role in acute ischemic stroke. To investigate the role of the circular RNA Rap1b (circRap1b) in acute ischemic stroke, in this study we established an in vitro model of acute ischemia and hypoxia by subjecting HT22 cells to oxygen and glucose deprivation and a mouse model of acute ischemia and hypoxia by occluding the right carotid artery. We found that circRap1b expression was remarkably down-regulated in the hippocampal tissue of the mouse model and in the HT22 cell model. In addition, Hoxa5 expression was strongly up-regulated in response to circRap1b overexpression. Hoxa5 expression was low in the hippocampus of a mouse model of acute ischemia and in HT22-AIS cells, and inhibited HT22-AIS cell apoptosis. Importantly, we found that circRap1b promoted Hoxa5 transcription by recruiting the acetyltransferase Kat7 to induce H3K14ac modification in the Hoxa5 promoter region. Hoxa5 regulated neuronal apoptosis by activating transcription of Fam3a, a neuronal apoptosis-related protein. These results suggest that circRap1b regulates Hoxa5 transcription and expression, and subsequently Fam3a expression, ultimately inhibiting cell apoptosis. Lastly, we explored the potential clinical relevance of circRap1b and Hoxa5 in vivo. Taken together, these findings demonstrate the mechanism by which circRap1b inhibits neuronal apoptosis in acute ischemic stroke.
