Figure 5. Correlation of microenvironment related prognostic genes’ expression with immune infiltration level. (A) Kaplan-Meier survival curve of 7 microenvironment related prognostic signature. (B) Immune cell infiltration analysis. A correlation coefficient of <0.3 indicates no correlation and a value of >0.3 indicates a positive correlation. (C) UALCAN website analysis CD74, HLA-DRB5, HLA-DRB1 and ACP5 protein expression. *P < 0.05, ** P < 0.01, *** P < 0.001.
