(a) The Kaplan–Meier curves. CHIT1, AMY1B, and LYZ were KM curves for genes whose upregulation prolongs median survival in patients with HNSCC. Others were KM curves for genes whose downregulation could prolong the median survival of HNSCC patients. (b) PPI network diagram of silibinin for HNSCC. (c) Differential expression analysis of intersecting genes in HNC.
