Sarm1 is Essential for Anesthesia-Induced Neuroinflammation and Cognitive Impairment in Aged Mice.
Article in Cellular and molecular neurobiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled it.
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
Postoperative cognitive dysfunction (POCD) is a common phenomenon among elderly patients with unclear etiology. Sterile alpha and TIR motif-containing 1 (Sarm1) plays important roles in neuroinflammation and cognitive function, and activates Calpain which has been shown to promote POCD through TrkB cleavage. This study aims to test the hypothesis that Sarm1 is involved in POCD through regulating Calpain activity. Wild type and Sarm1 knock out mice were exposed to isoflurane. Mouse cognitive function was determined by Morris water maze test. Neuroinflammation was determined by Iba1 and GFAP protein levels and mRNA expression of proinflammatory cytokines. Calpain activation was determined by αII-spectrin degradation and TrkB cleavage. Mitogen-activated protein kinase (MAPK) signaling was determined by c-Jun N-terminal kinase and cJun phosphorylation both in vivo and in vitro by Western blot and immunofluorescence staining. We found that Sarm1 deletion suppressed isoflurane induced cognitive impairment and neuroinflammation. Deletion of Sarm1 inhibited isoflurane induced αII-spectrin degradation and TrkB cleavage, which indicates suppression of Calpain activation. Finally, deletion of Sarm1 suppressed isoflurane induced MAPK signaling both in vivo and in vitro. Our findings suggest that isoflurane anesthesia induced cognitive impairment is prevented by Sarm1 deletion in mice, making Sarm1 a potent therapeutic target for treating or preventing POCD.
