Relation between resistance to in vitro spontaneous cell death and ID protein expression levels in 14 CLL samples. Relative numbers of viable cells were determined from MTT assay data after 72 hrs culture; data points show the mean ± SEM. Data for relative ID expression levels are given in Figure 5B in the main manuscript. The left-hand plots show linear regression analysis where samples are coded according to ID protein expression range (open triangles: lowest 25th percentile; open squares: highest 75th percentile; solid diamonds: remaining samples). The right-hand plots show a comparison of ID protein expression levels between samples grouped according to percentile range of ID protein expression. Significant (<0.05) P values, calculated by Student’s t-test, are indicated in bold-face.
