CYGB and nasopharyngeal carcinoma: According to the minimum OOB, three variables including dNLR (HR = 1.14; 95% CI 1.05–1.23; P = 9.14 × 10–4), HGB (HR = 0.98; 95% CI 0.97–0.99; P = 5.24 × 10–3) and EBV DNA (HR = 1.59, 95% CI 1.32–1.93, P = 1.22 × 10–6) were found to be significantly associated with OS among NPC patients (Fig. 1B).
