EBV-associated gastric carcinoma: four-gene immunoscore

Title: EBV-associated gastric carcinoma: four-gene immunoscore — gene expression data, immunoscore coefficients, and clinical data for EBVaGC and EBVnGC samples. Overview This dataset contains the minimal, reproducible materials required to verify the analyses reported in the manuscript “Immune Hub Genes and a Proof-of-Concept Prognostic Signature in EBV-Associated Gastric Carcinoma (EBVaGC).” We provide (i) sample ID lists used to subset publicly available cohorts (TCGA-STAD, GEO: GSE51575, GSE62254), (ii) the four-gene risk-score coefficients, (iii) derived per-sample immunoscores and group labels for discovery/validation cohorts, and (iv) minimal R scripts to reproduce the key figures and statistics (Figure 4 IHC plot, Kaplan–Meier curves, time-dependent ROC, and C-index). Data source policy Raw transcriptomic data are not re-distributed here; they remain available from public repositories as cited (TCGA-STAD; GEO: GSE51575, GSE62254). The provided sample indices allow users to retrieve the identical subsets, or users may rely on the included derived immunoscore tables to reproduce all figures without re-downloading raw matrices.
