Partition for controls, B-CLL, and MCL samples induced by the joint CART analysis.

The decision tree induced by the joined CART analysis is built from rules for CDK4 and CCND1 expression levels. Scatterplot shows the regions as defined by the decision tree. These regions are indicated by large digits. Individual data points are marked by their group membership (C, control; B, B-CLL; M, MCL). Only cases are drawn if expression values were computed for both genes,CDK4 and CCND1. The single MCL without the t(11;14)(q13;q32) translocation is highlighted by an asterisk.
