Ficoll‐isolated BM mononuclear cell RNA samples of cohort #2 consisted of MDS n = 48 and ‘Hematological malignancies’ n = 11. For patients diagnosis and normalized fold changes of cohorts #1 and #2, see Table S1. BM plasma samples of cohort #3 consisted of MDS n = 45, MDS 5q‐ n = 12, AML n = 10, and non‐MDS n = 12. For patients diagnosis, see Table S2.
