Survival analyses. (A) Kaplan-Meier survival analyses of overall survival of 1,127 patients enrolled onto Southwest Oncology Group (SWOG) trials from 1986 to 2009 and 2,238 patients treated at MD Anderson Cancer Center (MDA) from 1995 to 2009 for newly diagnosed acute myeloid leukemia (non–acute promyelocytic leukemia). (B) Plots of probability of death in specific week given that patient was alive at beginning of week (weekly hazard) for patients enrolled onto SWOG trials or treated at MDA. (C-E) Weekly hazard plots for all patients enrolled onto SWOG trials or treated at MDA, stratified by age ([C] ≤ 60, [D] 61-70, [E] > 70 years of age). Slopes of changes in weekly mortality tended to decrease after week 3 in SWOG and week 4 in MDA for patients age 60 years or younger and those older than age 70 years; for patients age 61 to 70 years, slopes tended to decrease after week 4 in SWOG and after week 3 in MDA, respectively.
