Analysis of differences in immune function between the high-risk group and low-risk group. Blue represents low-risk, red represents high-risk, “∗” represents the difference in immune function between the two groups, and “∗∗∗” represents the significant difference. The results of immune function analysis showed that, compared with the high-risk group and the low-risk group, the two immune functions of type II IFN response and type I IFN response were suppressed, and the function of major histocompatibility complex I (MHC I) was enhanced.
