Ideogram of the genomic imbalance of ABC and GCB DLBCLs. Summary of the chromosomal imbalance of 28 patients in the ABC group (A) and 18 patients in the GCB group (B). Lines on the left (red) of the ideogram indicate losses, and those on the right (green) indicate gains. Red squares represent homozygous losses (log₂ ratio < -1.0) on the left, and green squares high-level gains (log₂ ratio > +1.0) on the right.
