Identification of key immune cells. A: Difference analysis of immune cell infiltration between IA group and normal control group. The Wilcoxon test was used to statistically analyze the difference of immune cell infiltration between IA and normal control groups. * represents P < 0.05; ** represents P < 0.01; *** represents P < 0.001; **** represents P < 0.0001; ns represent no significant difference. P < 0.05 was considered statistically significant. B: The partial likelihood deviance for the lasso regression; C: The lasso regression analysis; D: Mean decrease accuracy ranking of 23 immune cells
