Expression level of these key TIICs-related genes and their prognostic value in LUAD patients. Box-plots comparing the expression differences of CCR2 (A), LCP2 (D), and PTPRC (G) in normal tissues and LUAD tissues of female patients. Box-plots comparing the expression differences of CCR2 (B), LCP2 (E), and PTPRC (H) in paired tumor and adjacent normal tissues of female patients. Kaplan–Meier plots of different CCR2 (C), LCP2 (F), and PTPRC (I) expression levels in female patients. Box-plots comparing the expression differences of BTK (J) and CCR2 (M) in normal tissues and LUAD tissues of male patients. Box-plots comparing the expression differences of BTK (K) and CCR2 (N) in paired tumor and adjacent normal tissues of male patients. Kaplan–Meier plots of different BTK (L) and CCR2 (O) expression levels in male patients. A p < 0.05 was considered to be statistically significant
