  1. Contingency table of r-groups and p-groups of the two test data sets (De Preter and McArdle/Wilzén), 47 samples in total. The r-group assignment was based upon MNA status, INSS stage and expression levels of the six NB-associated genes with the highest PubMed search score (see additional file 4). ND = Not determined. The p-group assignment was based upon the PCA clusters (see text for details).
