Latent Epstein-Barr Virus Infection Correlates with Glycosphingolipid Enrichment and Morphological Remodeling of Extracellular Particles.
Article in Biology, 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
Epstein-Barr virus (EBV) is causally associated with various malignancies and autoimmune diseases. It establishes a lifelong latent infection in host B-lymphocytes, and can strategically manipulate host cell metabolism and cell-to-cell communication via extracellular particles (EPs). While EBV-induced changes in fatty acid and mevalonate pathways are documented, the role of the sphingolipid network in this process remains poorly understood. In this study, we characterized both the EP and the cellular sphingolipid signatures of three EBV-infected (EBV+) lymphoblastoid cell lines compared to three EBV-negative (EBV-) counterparts. Lipidomic analysis revealed a profound metabolic redirection in EBV+ cells, characterized by reduced ceramide and sphingomyelin levels, and a significant upregulation of glycosphingolipids (GSLs), particularly hexosylceramide and globotrialosylceramide. Furthermore, EBV+ cells released larger, more heterogeneous EPs that are significantly enriched in GSLs and in the viral non-coding RNA
