Meta-analysis to assess overlap between the 885 probe sets differentially expressed between responders and nonresponders in the training set, and 2 previously published datasets. The histograms represent the results of 10 000 simulations to determine the probability of seeing a concordance equal to or greater than what we observed. (A) Comparison with a gene profile of blastic versus chronic phase reported by Zheng et al.¹⁶  (B) Comparison with a gene profile of patients with short versus long duration of chronic phase on treatment with nonimatinib therapy reported by Yong et al.²¹
