Copy number changes detected by CGH in 23 follicular lymphomas from 18 patients (a) and 35 transformed DLBCLs from 28 patients (b). Each line represents one alteration detected in one tumor, with losses indicated to the left and gains to the right of the ideograms. Thick lines indicate high-level amplifications. In cases with more than one sample analyzed of the same diagnosis (follicular lymphoma or transformed DLBCL), each alteration was counted once.
