To investigate the prognostic impact of CERCAM expression in clinicopathological subgroups of HNSCC patients, we did Cox regression analysis of OS, DSS, and PFI values for each subgroup of patients in TCGA-HNSCC, and the results are shown in the form of forest plots (Fig. 5), and information on specific statistical values of OS, DSS, and PFI for each clinicopathological subgroup of patients is shown in Table 3. The gene discussed is CERCAM; the disease is head and neck squamous cell carcinoma.
