Receiver operating characteristic (ROC) curve analyses of cut-off points of baseline absolute lymphocyte and monocyte counts and lymphocyte-to-monocyte ratio (LMR) for overall survival (OS) analyses among patients with metastatic nasopharyngeal carcinoma (NPC). The cut-off points of the lymphocyte count (a), monocyte count (b), and LMR (c) for OS analyses were 1.390 × 10⁹/L, 0.665 × 10⁹/L, and 2.475, respectively. AUC, area under the ROC curve
