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
backgroundSepsis-induced organ dysfunction poses a significant clinical challenge with limited therapeutic options. This study investigated the therapeutic potential of the glucagon-like peptide-1 receptor agonist (GLP-1RA) liraglutide in sepsis and its underlying mechanisms, focusing on modulation of the gut microbiota-derived metabolome.
methodsPublic transcriptomic data analysis identified overlapping targets between liraglutide and sepsis-related genes. In a murine cecal ligation and puncture (CLP) model, liraglutide treatment was evaluated for its effects on survival, systemic inflammation, and organ injury. The gut microbiota composition and fecal metabolome were assessed via 16S rRNA sequencing and UPLC-MS. We also measured plasma GLP-1 in sepsis patients and examined the microbiota-dependency of liraglutide's effects using antibiotic-depleted mice and fecal microbiota transplantation (FMT) from liraglutide-treated mice. Additionally, citrulline, a key identified metabolite, was functionally validated both in vitro and in a clinical cohort.
resultsLiraglutide significantly improved survival, reduced pro-inflammatory cytokines, and alleviated lung, liver, and colon damage in septic mice. It partially restored sepsis-induced gut dysbiosis and modulating associated metabolites, including increasing citrulline. The survival benefit of liraglutide was abolished in microbiota-depleted mice, while FMT from liraglutide-treated mice conferred protection against sepsis, confirming the gut microbiota as a critical mediator. Furthermore, citrulline exhibited direct anti-inflammatory properties in cellular assays, and its plasma levels were negatively correlated with sepsis biomarkers (PCT and CRP) in patients.
conclusionsTaken together, our findings indicate that liraglutide mitigates sepsis by modulating the gut microbiota and regulating associated metabolic pathways. Citrulline may represent a potential microbial mediator or exploratory biomarker within this axis, warranting further mechanistic investigation.
