Interplatform performance of the BAGS2Clinic assay. (A) Histogram of correlations between gene expression obtained using nCounter (NanoString Technologies) or the Human Genome U133 Plus 2.0 microarray (Affymetrix) from a pilot study of 14 OCT DLBCL samples; the 0.8 cutoff value was used to select highly correlated genes (indicated by a vertical red dotted line). (B) Confusion matrix of the assignment of DLBCL to BAGS subtypes by the gold standard (1) vs the BAGS2Clinic assay on a subset of the independent validation cohort (n = 70).
