Number of additional abnormalities associated with each CNA. The average numbers of abnormalities per tumor for tumors with a specific CNA were analyzed in FL and tFL (av. abnl. FL, av. abnl. tFL) and are presented in ascending order according of the av. abnl. FL. The distribution of the number of cases falling within the noted ranges of abnormalities is displayed with bar graphs. The number of cases with an rCNA in FL and tFL (number FL, number tFL) and the ratio of the frequency in tFL to FL are shown. rCNAs that are ∼2 or more times as frequent in tFL are boxed, and frequencies that differ significantly between FL and tFL by the Fisher exact test are marked with an asterisk (*).
