Sinusoidal cell-derived biomarker scores predict diagnosis and prognosis in chronic liver disease.
Article in BMC medicine, 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
backgroundSinusoidal cells are central drivers of chronic liver disease (CLD) progression, yet current biomarkers fail to capture their phenotypic states. We aimed to develop sinusoidal cell-specific biomarkers for the diagnosis and prognosis of CLD.
methodsSingle-cell RNA sequencing data were analyzed to identify cell-type-specific signatures for liver sinusoidal endothelial cell capillarization, hepatic stellate cell activation, and macrophage polarization. These signatures were integrated into three sinusoidal scores (endothelial, mesenchymal, and macrophage) reflecting dedifferentiation of each cell type. Scores were evaluated in an internal cohort (n = 108) and validated in three independent cohorts (total n = 1008), including patients with 2-year follow-up. Gene expression was quantified in routine or previously archived liver biopsy samples, allowing assessment without additional invasiveness to patients and ensuring global feasibility.
resultsThe sinusoidal scores were significantly elevated in patients with advanced disease and correlated with key clinical endpoints: decompensation (AUROC = 0.896), portal hypertension (HVPG > 12 mmHg, AUROC = 0.788), and impaired liver function (MELD > 10, AUROC = 0.898, Child-Pugh B, AUROC = 0.920; Child-Pugh C, AUROC = 0.894). At baseline, scores predicted both fibrosis progression from F3 to F4 (AUROC = 0.827) and clinical decompensation (AUROC = 0.971), as well as fibrosis regression (AUROC = 0.893) and HVPG improvement (AUROC = 0.838) during follow-up.
conclusionsSinusoidal cell-derived scores capture biologically relevant pathways of CLD progression and regression and can be measured from existing biopsy material available in most centers worldwide. Despite their retrospective derivation, these scores hold strong promise for prospective validation and clinical implementation as tools for patient stratification, monitoring, and therapeutic guidance.
