Exosome-Associated Gene Signature for Predicting the Prognosis of Ovarian Cancer Patients

Figure 2

Prognostic analysis of exosome-related gene prognostic risk models in TCGA training set, TCGA testing set, entire TCGA dataset, and GEO dataset. (a–d) Distribution of risk scores, survival status, and expression of four prognostic genes in the four datasets. (e–h) In the four datasets, Kaplan-Meier analysis was used to compare the overall survival of patients in the high-risk and low-risk groups (). (i–l) ROC curves for the predictive power of prognostic risk models in the four datasets. (m–p) Plots of principal component analysis in the four datasets.
