Scatter plots illustrating the relationship between prediction power and number of hypo-up genes in classifier. a Gene expression classifier. x-axis represents the number of hypo-up genes in the classifier and y-axis represents the AUC value of the ROC curve for the classifier. AUC stands for area under the curve. ROC stands for receiver operating characteristic. b Gene methylation classifier based on all region CpGs. c Gene methylation classifier based on dominant methylation-altered regions
