As expression data in chronic myeloid leukaemia (CML) or acute lymphoblastic leukaemia (ALL) are not covered by the SurvExpress database, we switched to a different platform (Genevestigator; https://genevestigator.com/gv/; Hruz et al, 2008) which provides data of BCR/ABL1‐driven diseases. Here, BCR is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
