A–C: A and B show frequencies of genome copy number gains and losses in luminal and basal breast tumors, respectively (Fridlyand et al., 2006). C shows univariate statistical assessments of differences between the two tumor types.
D–F: D and E show frequencies of genome copy number gains and losses in luminal and Basal B breast cancer cell lines, respectively. F shows univariate statistical assessments of differences between the two cell line types. p values of 0.05 and 0.01 are indicated as in C. All data are plotted beginning at chromosome 1pter to the left and ending at Xqter to the right. Vertical solid lines indicate chromosome boundaries. Vertical dashed lines indicate centromere locations. p values of 0.05 and 0.01 are indicated by dashed horizontal lines in C and F.
