ROC analysis of the sensitivity and specificity of the overall survival prediction by the six-pseudogene risk score, IDH1 status, MGMT expression level, gender and age in CGGA data set. P values were from the comparisons of the area under the ROC (AUROC) of six-pseudogene risk score versus those of MGMT expression level, IDH1 status, gender and age, respectively. As can be seen, the six-pseudogene risk score showed a better prediction of overall survival than age, IDH1 status, and MGMT expression level.
