From: Establishment of age group classification for risk stratification in glioma patients
ROC curve of the sensitivity and specificity for diagnosing WHO IV glioma (a) and high grade glioma (b). Age, ki-67 and positive area of wt-p53 have great value for the diagnosis of WHO grade IV glioma and high-grade glioma. The proportion of WHO grade IV glioma (c), astrocyte differentiation (d), oligodendrocyte differentiation (e), ependymal cells differentiation (f) and >4 cm of tumor size (g) in four age groups. According to the discriminant classification of whether the pathological diagnosis of the patients was WHO grade IV or not, the prediction probability was taken as the discriminant dividing point, and the total judgment rate was 74.0% (h)
