Long-term success in withdrawing all immunosuppressive treatment. Results were analyzed according to the presence or absence of (A,E) prior treatment change and prednisone (PDN) doses at (B-D) 6 and (F-H) 12 months after initial treatment. Withdrawal of all immunosuppressive treatment after resolution of GVHD among patients without recurrent malignancy was counted during any line of treatment in A and E and during initial treatment among patients initially treated with steroids in B-D and F-H. Patients with recurrent malignancy before the landmark were excluded in all analyses, and patients with treatment change before the landmark were excluded in the analyses shown in B-D and F-H.
