Model I: Adjusts for sex + age; Model II: adjusts for Model I + FAB subtype + bleeding + prognostic stratification + Pulmonary infection + chemotherapy; Model III: adjusts for Model II + BM blast + AT + ALB + Crea + HDL + TG + Glu + CK-MB + Myo + SF + WBC. Dummy variables were used for SF; WBC was entered as a categorical variable
