Gene Expression Analysis of an EGFR Indirectly Related Pathway Identified PTEN and MMP9 as Reliable Diagnostic Markers for Human Glial Tumor Specimens

Figure 4

Classification tree derived from the combined measurement of PTEN and MMP9 quantitative expression. At each root, diagnostic classes are divided following the absolute quantification and expressed in femtograms. Probabilities values (𝑃) for the different classes are reported.
