Lipidomic Expression Analysis in Carotid Atherosclerotic Disease: A Systematic Review.
Synthesis in Annals of vascular surgery, 2025. 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
backgroundLipids are key molecules for atherosclerosis, with tight regulation mechanisms, making them potential biomarkers for disease-specific diagnostics and therapeutics. Therefore, we aim to perform a systematic literature review on lipidomic analysis in serum/plasma and plaque samples of patients with carotid atherosclerosis.
methodsWe performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines on the lipidomic profile in serum/plasma and carotid artery plaques from patients with significant carotid disease by degree of stenosis in preoperative imaging and clinical presentation (symptomatic, asymptomatic, and radiation-induced carotid disease). Main outcome was the differential lipidomic expression of serum/plasma, and plaque lipids of patients with carotid artery atherosclerosis. Studies were screened using the Newcastle-Ottawa Scale to determine the quality of the design and content of the selected manuscripts.
resultsWe included fourteen studies, from which ten included plaque analysis. The lipidomic analysis revealed that sterols and hydroxycholesterols were consistently found in both blood and plaque across studies. Triacylglycerols were present in both sample types, with specific forms linked to radiation-induced carotid artery disease. Symptomatic patients exhibited esterified hydroxyeicosatetraenoic acids and arachidonic acid precursors exclusively in plaque with an inflammatory profile of the disease. In contrast, docosahexaenoic acid and eicosapentaenoic acid were associated with plaque stability. Diabetics showed nonesterified fatty acids and specific phospholipids only in plaque, indicating localized lipid changes. Other pathways relevant to disease progression include the sphingolipids and ceramide pathways with inflammatory profiling.
conclusionLipidomic provides an innovative approach to stratify carotid atherosclerotic disease. Integrating lipidomic data with other -omics approaches may further enhance our understanding of disease mechanisms and aid in the development of precision medicine approaches, specifically in those patients at risk for early carotid atherosclerotic disease.
