Metabolic phenotyping of sepsis in large multicenter cohorts: identification of a reproducible high-risk subgroup.

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 represents a profound metabolic crisis, yet the prognostic significance of glycolipid biomarkers remains unclear. Most prior studies examined single metabolic indicators, overlooking their combined effects on organ dysfunction and survival. This study aimed to identify glycolipid-related biomarkers predicting outcomes in sepsis and to define a reproducible metabolic phenotype linked to multi-organ dysfunction and mortality.
methodsWe conducted a multicenter retrospective cohort study of 2,970 adults with sepsis admitted to three tertiary hospitals in China (2015–2023), with external validation using the international MIMIC-IV database (2008–2019). A comprehensive panel of glycolipid markers was evaluated through univariable Cox and LASSO regression, supported by tree-based machine learning and logistic regression for sepsis-associated acute kidney injury. Low-density lipoprotein cholesterol (LDL-C) and the triglyceride–glucose (TyG) index emerged as the most consistent prognostic biomarkers and were used to define metabolic phenotypes.
resultsAmong 2,970 patients (median age 68 years [IQR 60–80]; 62.5% male), LDL-C and TyG independently predicted mortality across statistical and machine-learning analyses. Patients with a high TyG–low LDL phenotype exhibited the most severe multi-organ dysfunction—renal, hepatic, coagulative, and inflammatory—and the highest mortality risk (HR 1.31, 95% CI 1.04–1.65). Validation in MIMIC-IV confirmed the reproducibility of this phenotype across populations and healthcare systems.
conclusionsIntegrating LDL-C and TyG identifies a reproducible metabolic phenotype marking sepsis patients at high risk of multi-organ failure and death, offering a simple framework for early risk stratification and personalized management in critical care.
