Glioma grade as a function of tumor size and time. Tumor grade as a function of tumor size and time for each of the five diffusion-proliferation (D−ρ) combinations: (a) low diffusion-low proliferation, (b) high diffusion-low proliferation, (c) low diffusion-high proliferation, (d) high diffusion-high proliferation, (e) medium diffusion-medium proliferation. Blue part: grade II radius, green part: grade III radius, red part: Grade IV radius.
