Thirty-seven radiomic features correlated with CD8+ TILs in NSCLC (rho = -0.289 to 0.310, p < 0.05), among which NGLDM_Contrast has a strong correlation with CD8+ TILs with the largest linear correlation coefficient (rho = 0.310, p = 0.001; Supplemental Table 3). The gene discussed is CD8A; the disease is non-small cell lung carcinoma.
