CD4 and neoplasm: Compared to the low-risk group, the high-risk group had a higher proportion of most tumor immune cells (Figure 8B), including initial B cells (p < 0.001), dormant CD4 memory cells (p = 0.0081), dormant natural killer cells (p = 0.145), M1-type macrophages (p = 0.0014), and M2-type macrophages (p < 0.001).
