Fig. 4From: Quantitative proteomic analysis shows differentially expressed HSPB1 in glioblastoma as a discriminating short from long survival factor and NOVA1 as a differentiation factor between low-grade astrocytoma and oligodendrogliomaa ROC curves comparing HSPB1 expression levels of NN group compared to each grade of malignant astrocytomas, grade II to IV. The values of area, standard error under the nonparametric assumption, and asymptotic significance considering null hypothesis of true area - 0.5; b Kaplan-Meier curves. Overall survival time of GBM cases presenting HSPB1 expression level > 23.28 (3 fold of cut off value determined by ROC curve) (n = 29) compared to GBM cases presenting HSPB1 expression level < 23.28 (n = 48).
