1 · What the graph read from 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.

2 · The registry

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

Chemotherapy-induced nausea and vomiting (CINV) is a debilitating side effect related to activation of substance P (SP). SP activation can result from dysregulation of the gut-brain axis, and also from activation of protein kinase A signaling (PKA) signaling. In this study, we connected these factors in an attempt to unveil the mechanisms underlying CINV and develop new therapeutic strategies. Female rats were injected with cisplatin (Cis) to induce pica. Fecal samples were collected before/after injection, and subjected to lipid metabolomics analysis. In another portion of pica rats, the PKA inhibitor KT5720 was applied to investigate the involvement of PKA signaling in CINV, while fecal microbiota transplantation (FMT) was implemented to verify the therapeutic effect of the lipid metabolite 14(15)-EpETE. Pica symptoms were recorded, followed by ileal histological examination. The targeting relationship between 14(15)-EpETE and glucagon was determined by bioinformatics. SP and glucagon/PKA signaling in rat ileum, serum, and/or brain substantia nigra were detected by immunohistochemistry, enzyme-linked immunosorbent assay, and/or western blot. The results showed a significantly lower level of 14(15)-EpETE in rat feces after Cis injection. KT5720 treatment alleviated Cis-induced pica symptoms, ileal injury, SP content increase in the ileum, serum, and brain substantia nigra, and ileal PKA activation in rats. The ileal level of glucagon was elevated by Cis in rats. FMT exerted an effect similar to that of KT5720 treatment, relieving the Cis-induced changes, including ileal glucagon/PKA activation in rats. Our findings demonstrate that FMT restores 14(15)-EpETE production, which inhibits SP release by targeting GCG/PKA signaling, ultimately mitigating CINV.
