  1. The 6 validation datasets with regard to the platform used in the original experiment, the number of unique genes represented in the platform, the number of samples that are primary tumors or distant metastases (mets), the number of genes in the common metastatic signature (CMS) represented in the platform, the number of CMS genes that were significant with a Q-value < 0.1, the LS statistic p-value, and the Gene Expression Omnibus Accession number (GEO Acc #) or SMD Publication number (SMD Pub #).
