Construction of a nomogram. (A,B) Univariate Cox analysis demonstrated that clinical factors, including risk score, age, clinical stage, T stage, and N stage, were statistically correlated to prognosis, and the multivariate Cox analysis demonstrated that risk score, age, and N stage were independent prognostic risk factors. (C) A nomogram for predicting 1-year, 3-year, and 5-year prognosis. (D) The calibration curves for predicting 1-year, 3-year and 5-year prognosis.
