Figure 5. Correlation between the LUAD 6-irlncRNA pair signature and immune cell subtype infiltration. (A) Estimation of the infiltrating immune cells by TIMER, CIBERSORT, xCELL, quanTIseq, MCPcounter, EPIC, and CIBERSORT-ABS. (B–D) High-risk patients exhibited higher content of B cells (B), CD4+ T cells (C), and M2 macrophages (D) compared to the low-risk patients.
