We analyzed survival data from 271 HNSCC patients in the TCGA database, dividing them into two groups based on IFNG expression: a high expression group (n = 126) and a low expression group (n = 145), using a cutoff value of 0.3815 determined by Receiver Operating Characteristic (ROC) analysis (Table 1). The gene discussed is IFNG; the disease is head and neck squamous cell carcinoma.
