IHC-based correlation analyses of CD8+ T cells vs. immune and viral defense markers in LUAD TMAs
(A) LUAD H-score-based Spearman’s rank correlation similarity matrix, one minus Spearman’s rank correlation-based clustering (n = 128).
(B) LUAD H-score-based correlation forest plot for panel markers vs. CD8α H-score, Spearman’s rank correlation (rho with 95% confidence interval depicted). ∗ Indicates an adjusted p value less than 0.05 after FDR 0.05 multiple comparisons correction two-stage linear step-up procedure of Benjamini, Kriegerm, and Yekutieli (n = 128).
(C) LUAD H-score-based correlation forest plot for panel markers vs. CD8α infiltration score, Spearman’s rank correlation (rho with 95% confidence interval depicted). ∗ Indicates an adjusted p value less than 0.05 after FDR 0.05 multiple comparisons correction two-stage linear step-up procedure of Benjamini, Kriegerm, and Yekutieli (n = 128).
(D) Representative NSCLC LUAD, paraffin archive to show the prioritized 4-marker IHC panel with H&E for morphologic reference. All IHC stains were scored by modified H-score with a primary focus on CD8 T cells and tumor infiltrative pattern. Tumors are arranged top to bottom by high to low CD8α H-scores, respectively. 100x–400x total magnification. Representative scale bar provided in top left image of figure panel.
