THYM showed a strong correlation (r = 0.42 ∼ 0.77, all p < 0.05), while LICH (r = 0.12 ∼ 0.33, all p < 0.05) and HNSC (r = 0.14 ∼ 0.31, all p < 0.05) showed week correlations between MXD3 expression levels and tumor infiltration of the six immune cell types, while HNSC-human papillomavirus-positive (HPVpos) showed good correlations of MXD3 expression levels with tumor immune infiltration only of B cells (r = 0.43, p < 0.05) and CD8 + T cells (r = 0.45, p < 0.05). Here, CD8A is linked to neoplasm.
