Major transplantation outcomes for patients with acute GVHD given either low-dose glucocorticoids (prednisone-equivalent dose of 1 mg/kg per day; dashed line) or standard-dose glucocorticoids (prednisone-equivalent dose of 2 mg/kg per day; solid line) for initial treatment of acute GVHD. Cumulative incidence of NRM (A) and recurrent malignancy (B), and Kaplan-Meier estimates of overall survival (C).
