Identification of risk score based on gene signature of patients with ovarain cancer in TCGA. A Risk plot of each point sorted based on risk score, representing one patient. Green and red points represent patients with low- and high-risk scores, respectively. B Distribution of risk score and significant genes of ovarian cancer in TCGA. C Kaplan–Meier analysis of ovarian cancer patients was stratified by median risk in TCGA. High risk scores are associated with poor survival. D ROC curves of risk score in prognosis prediction of ovarian cancer in TCGA. E DCA curves of risk score in prognosis prediction of ovarian cancer in TCGA
