Fig. 4. Kaplan-Meier curve based on TMED4 expression in OShnscc using default parameters of "TCGA" as data source, "OS" for survival, and "Upper 25%" for patients splitting. TMED4: transmembrane p24 trafficking protein 4 gene; OShnscc: Online consensus Survival tool for Head and Neck Squamous Cell Carcinoma; TCGA: The Cancer Genome Atlas; HNSCC: head and neck squamous cell carcinoma; TNM: tumor node metastasis; mRNA: messenger RNA; HR: hazard ratio; CI: confidence interval; OS: overall survival; HPV: human papilloma virus; DFI: disease-free interval; PFI: progression-free interval.
