Investigation of immune status in different risk groups. (A) Heatmap revealing the immune and stromal cells infiltration in ESCC immune microenvironment. (B) Box plots showing the infiltration of the immune cells based on the Cibersort algorithm in different risk groups; *p < 0.05 and **p < 0.01. (C) Estimation of the coefficients for risk score with immune checkpoint genes. (D) Histogram showing the relationships between risk score and chemokines, receptors, MHC, immunoinhibitors, and immunostimulators.
