Table 1 Anatomopathological comparisons. Anatomopathological comparisons and the number of libraries in each class (n = normal, a = astrocytoma grades II and III, g = glioblastoma, a 2 = astrocytoma grade II, a 3 = astrocytoma grade III). The symbol "O" represents samples of the first group, and "X" represents samples of the second group in Figures 2 and 3.
