Kaplan-Meier probabilities of survival among patients with hematologic malignancies treated with allo-NMA-HCT as stratified into four risk groups based on a consolidated HCT-CI and KPS scale. Group I (solid black line) includes patients with HCT-CI scores of 0 to 2 and a KPS of > 80%; group II (dotted black line) includes patients with HCT-CI scores of 0 to 2 and a KPS of ≤ 80%; group III (solid blue line) includes patients with HCT-CI scores of ≥ 3 and a KPS of >80%; group IV (dotted blue line) includes patients with HCT-CI scores of ≥ 3 and a KPS of ≤ 80%. Survival rates at 2 years were 68%, 58%, 41%, 32% for risk groups I, II, III, and IV, respectively. (From Sorror et al., 2008.⁴⁵  Reprinted with permission. ©2008, Wiley InterScience.)
