Figure 2. Overall survival (OS) analysis based on the histological subclassifications.

Figure 2

a: Conventional Grade III gliomas (AA, AO and AOA) show significantly better prognosis than Grade IV gliomas (GBM, GBMO). b: GBMO presented longer survival compared to GBM, although it is statistically not significant (p = 0.068). c: Oligodendroglial tumor (“oligo”; AO, AOA, GBMO) shows significantly better prognosis compared to pure astrocytic tumor (“pure astro”; AA, GBM). d: The survival curve of AA patients is almost identical to that of GBM patients.
