The infiltration of immune cells in high-risk and low-risk groups. A The correlation analysis of the prognostic risk gene ARNTL2 expression and immune cell infiltration was conducted using the GSCA database. B The ESTIMATE algorithm was employed to compare the ESTIMATE score, immune score, and stromal score between the high-risk and low-risk groups. C, D The levels of immune cell infiltration in LUAD patients were compared between high-risk and low-risk groups using the MCPcounter (C) and CEBERSORT (D) algorithms. Statistical significance is indicated as *P < 0.05, **P < 0.01, ***P < 0.001
