Fig. 7From: Identification of four key prognostic genes and three potential drugs in human papillomavirus negative head and neck squamous cell carcinomaSurvival analysis of patients stratified by HPV status and hub gene expression in HNSCC, HPV-positive and HPV-negative HNSCC tissues. The overall survival (OS), disease-free interval (DFI), disease-specific survival (DSS) and progression-free interval (PFI) of patients stratified by the expression levels of AREG, C19orf57, STAG3 and CAV1 were showed (Log-rank test, P < 0.05)Back to article page
