Fig. 1AValidation of the developed scoring system in the validation cohort. (A) The 1-year overall survival (OS) rate was divided according to the risk groups (P=0.085). The post-hoc analysis illustrated a better 1-year OS rate in the low- or intermediate-risk groups than that in the high- or very high-risk groups (P=0.018, * is indicated in the for the pos-hoc analysis). (B) The cumulative incidence of non-relapse mortality (NRM) was significantly divided according to the risk groups (P=0.035), (C) whereas the cumulative incidence of relapse was not significantly different between the 4 risk groups (P=0.349). (D) A receiver operating characteristic curve analysis achieved an area under the curve (AUC) of 0.715 (95% CI, 0.658–0.772) for predicting NRM events 1-year post-allogeneic hematopoietic stem cell transplantation.
