The low-risk group had a higher level of immune cell infiltrations than that of the high-risk group, and the correlation analysis demonstrated that the risk score was negatively correlated with the levels of most immune cells, except for CD56 dim natural killer cells, eosinophilia, monocyte and type 17 T helper cells (Supplementary Figure S4(C)). The gene discussed is NCAM1; the disease is Increased total eosinophil count.
