HLA-DRA predicts an inflamed TME in NSCLC. A Expression levels of immunomodulators (MHC, receptors, chemokines, immunoinhibitors, and immunostimulators) in the high- and low-HLA-DRA groups in NSCLC. B Correlation between HLA-DRA expression and tumor purity in NSCLC. C Correlations between HLA-DRA expression and the levels of TIICs calculated using two algorithms. The color and the values indicate the Pearson correlation coefficient. D Expression levels of inhibitory and stimulatory immune checkpoints in the high- and low-HLA-DRA groups in NSCLC
