000-52.82, depth of invasion (OR 5.046, 95% CI 1.281-19.874) were independent risk factors of OLNM in early cN0 HPSCC. The ROC curve had an AUC of 0.811 (95% CI 0.713-0.909), which implies good discriminate capacity. The calibration curve and the Hosmer-Lemeshow test (P = 0.972) demonstrated good model fitted and high calibration. A nomogram model based on age, drinking history, histological differentiation of tumor, and depth of tumor invasion was successfully developed to predict occult cervical lymph node metastasis in patients
