Construction of the risk score model in the training set. A Four lymph node metastasis-associated genes were identified in multivariate Cox regression analysis; B Patients were divided into high- and low-risk groups according to the median of the risk score; C More dead patients were observed with higher risk score; D Heatmap showed the expressions of prognostic gene signature in high- and low-risk groups. E K-M analysis of high- and low-risk groups F-H ROC curves of 1-, 3- and 5-year survival prediction of cervical carcinoma patients
