1 · What the graph read from it

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.

2 · The registry

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

backgroundMyeloid antigen-presentation dysfunction is a central but incompletely translated immune state in hepatocellular carcinoma (HCC). This study aimed to develop a compact prognostic and recurrence model directly anchored in single-cell-defined myeloid antigen-presentation loss.

methodsIn this prognostic prediction-model development and validation study, GSE149614 was used as the single-cell discovery cohort. Tumor and normal myeloid cells were extracted, antigen-presentation (AP) module scores were calculated, and AP-loss candidate genes were identified using pseudobulk aggregation. Candidate genes were projected to TCGA-LIHC, GSE14520, and GSE76427 bulk transcriptomic cohorts. Survival-oriented model refinement was performed in GSE14520 using overall survival (OS) and recurrence-free survival (RFS), followed by validation with Kaplan-Meier analysis, Cox regression, fixed-time AUC, clinicopathological comparison, pathway scoring, targeted cell-cell communication analysis, and nomogram construction.

resultsA total of 13,784 myeloid cells were analyzed, including 8,209 tumor-infiltrating myeloid cells and 5,575 normal myeloid cells. Tumor-associated myeloid cells showed lower AP scores than normal myeloid cells (P = 0.04054). A compact six-gene signature consisting of SMOX, CSF1, AQP9, FLNB, COL7A1, and MXI1 was established. In GSE14520, the signature predicted poor OS (HR = 1.94, 95% CI: 1.41-2.65, P = 3.73e-05) and poor RFS (HR = 1.60, 95% CI: 1.23-2.08, P = 4.63e-04). In TCGA-LIHC, it also predicted inferior OS (HR = 1.49, 95% CI: 1.12-1.99, P = 5.83e-03). High-risk tumors showed enhanced glycolysis, hypoxia, epithelial-mesenchymal transition (EMT), angiogenesis, and IL6-JAK-STAT3 activity, with reduced antigen-presentation and IFNG response signals.

conclusionsWe report a compact single-cell-derived myeloid AP-loss signature for HCC prognosis and recurrence stratification. The model links clinical risk to a biologically interpretable myeloid dysfunction state and broader tumor microenvironment remodeling.
