Contingency table of p-group assignment and genomic subgroup assignment of the two test data sets (De Preter and McArdle/Wilzén). The p-group assignment was based upon the PCA clusters. The genomic subtypes were established based on INSS stage, MNA status, and Del11q status (see text for details). The highest numbers of cases of the p- and h-group assignments falling into a specific genomic subgroup category are shown in bold.
