Genes and probe sets included in the respective parts of the analysis. Shown is our strategy for selecting angiogenesis-related genes. On the initial set of 402 genes after review of Medline and the Cytokines & Cells Online Pathfinder Encyclopaedia as well as Ingenuity Pathway Analysis, PANP-derived judgment of expression (“presence” vs “absence”) was assessed, leading to 291 genes being present at least once. Of these, 83 genes with no exploratively attributable information (NI) on proangiogenic or antiangiogenic activity were excluded. For further analyses, the 100 proangiogenic and 58 antiangiogenic genes present at least once in the training (TG) and validation group (VG) were retained.
