(B) Correlation of the risk score with the immune score in HNSCC samples. (C) Correlation of the risk score with the stromal score in HNSCC samples. (D) Correlation of the risk score with the ESTIMATE score in HNSCC samples. (E) Comparisons of immune cells between the high-risk and low-risk groups.
