MDS flow-scores in MDS WHO subgroups RA with or without RS and RCMD with or without RS in combination with cytogenetics and in combination with transfusion dependency or disease progression. (A,B) Results for patients with MDS classified as RA with or without RS. (C,D) Results for patients with MDS classified as for RCMD with or without RS patients. In panels A and C, results are grouped according to cytogenetic risk. Results for 2 patients with RA with or without RS and 1 patient with RCMD case are missing in panel A and panel C, respectively, since no cytogenetics were available in these particular cases. In panels B and D, results are grouped according to transfusion dependency or disease progression. Circles define patients with CD7 expression on their myeloid progenitors; squares define those with CD56 expression. Horizontal bars are medians.
