vCGH prediction on an independent cohort of 176 DLBCLs. (A) Gain. (B) Loss. The gains or losses identified by CGH for the 190 DLBCLs were shown above the X-axis. The gains or losses predicted by vCGH for the 176 DLBCLs were shown below the X-axis. On X axis, each bar represents a cytoband ordered from pter to qter, from chr1 to chr18. On Y axis, the height of each bar indicates the number of cases horboring a gain or loss on a cytoband.
