Mean steroid doses, mean GVHD severity scores, and percentages of patients with complete response after randomization show no benefit of MMF for initial treatment of chronic GVHD. (A) Prednisone doses. (B) Mean National Institutes of Health severity scores and (C) prevalence of complete response (CR) across time among surviving patients without recurrent malignancy. (A,B) Bars represent ± SD. (C) The upper black curves represent relapse-free survival for reference. Changes in prevalence of CR (gray lines) can occur either with the onset or end of CR or with death or recurrent malignancy in the presence or absence of CR. In all panels: —, MMF group; and ----, control group.
