We observed positive correlations between the hTIL scores and percentages of total T, CD4+ T, and CD8+ T (Fig. 2b–d), but negative correlations between the hTIL scores and NK and NKT (Fig. 2k, m), showing that hTIL was associated with the degree of leukocyte infiltration in tumor tissue and leukocyte composition. Here, CD4 is linked to neoplasm.
