Adj. stands for adjuvant and chemo for chemotherapy. Merged OS refers to merged data sets with Overall Survival endpoint and Merged RFS refers to the merged data sets with Relapse Free Survival endpoint. The expression values of dual channel data were already -transformed. Among the data sets generated by Affymetrix, the absolute intensity values of GSE3143, GSE2034 and GSE2990 were -transformed for this study as the rest of Affymetrix data sets were already - transformed by the authors.
