The results were as follows; the expression level of CFHR3 had a positive relationship with the infiltrating levels of B cells (r = 0.354, p = 3.67e − 02), neutrophils (r = 0.364, p = 3.15e − 02), macrophages (r = 0.613, p = 9.00e − 05), but negatively correlated with tumor purity (r = −0.207, p = 2.25e − 01), CD8+ T cell (r = −0.477, p = 3.79e − 03), and monocytes (r = −0.414, p = 1.33e − 02) (Figure 5(b)). This evidence concerns the gene CD8A and neoplasm.
