Distribution of the quantitative changes of each single chromosome. Graphical presentation of the results of the automated analysis of the SCCN strings of the karyotypes of 94 Ph positive ALL cases with respect to quantitative chromosome changes. The number of events leading to loss (left side) or gain (right side) of chromosomal material are depicted in bars projecting onto the (sub)bands of the respective chromosome ideogram. The lengths of the bars are relative to the maximum number of losses or gains of the respective chromosome. The minimum and maximum values are given.
