GBP5 and lip and oral cavity carcinoma: We found that high gene expression levels of GBP5 were associated with shorter overall survival (OS) in oral cancer patients with poor cell differentiation (adjusted hazard ratio (AHR) = 1.49, 95% confidence interval (CI) = 1.01–2.21, p = 0.047, Table 2) and associated with poor disease-free survival (DFS) in oral cancer patients with poor cell differentiation (AHR = 1.81, CI = 1.03–3.19, p = 0.040, Table 3) and lymph node metastasis (AHR = 2.21, CI = 1.09–4.50, p = 0.028, Table 3).
