A longitudinal plasma metabolomics dataset of sepsis-associated liver injury across multiple clinical time points.
Article in Scientific data, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Sepsis-associated liver injury is a severe complication of sepsis characterized by substantial metabolic alterations, yet longitudinal metabolomics resources for this condition remain limited. Here, we present an LC-MS-based longitudinal metabolomics dataset comprising 88 blood samples collected from healthy controls and sepsis patients with or without liver injury across multiple ICU-associated clinical time points. Comprehensive metabolomic profiling generated 18,247 high-quality metabolic features and 2,894 annotated metabolites, providing a resource for investigating temporal metabolite patterns with annotations related to nucleotide, lipid, and bile acid metabolism across clinical groups and sampling time points. Exploratory analytical approaches, including temporal clustering, weighted correlation network analysis, and regularized regression-based feature selection, were applied to facilitate characterization of longitudinal metabolic patterns within the dataset. This dataset provides a reusable resource for future studies on longitudinal metabolic dynamics, biomarker validation, integrative multi-omics analyses, and methodological development in sepsis and critical care research.
