As shown in Fig. S7, CYT was highly correlated with the cell fractions of CD8+ T cell and activated NK cell evaluated in the corresponding bulk tumor tissues (Pearson correlation coefficient = 0.73, P < 1E‐20), while extremely low correlation was detected between the cell fraction of resting NK cell and CYT (Pearson correlation coefficient = 0.07). The gene discussed is CD8A; the disease is neoplasm.
