Quantitative evaluation of the tissue area exhibiting IGFI (A), IGFII (B), IGF-IR (C) or IGF-IIR (D) immunopositivity (LI, labelling index) in normal brain and glioblastoma samples. Each dot shows the value associated with one case. The horizontal line corresponds to the median. Only the significant differences are indicated as **P<0.01 and ***P<0.001.
