ROC evaluating diagnostic effectiveness and building a predictive nomogram. A ROC curve was plotted for 1-, 3- and 5-years overall survival in the TCGA group. B Nomogram to predict the 1-years, 3-years and 5-years overall survival of OV patients. C Calibration curve for the overall survival nomogram model in test group. D ROC curve was plotted for 1-, 3- and 5-years overall survival in the ICGC group. E Kaplan–Meier survival curve results in ICGC groups
