Estimated cumulative incidence function for time to death prior to appropriate therapy (T2) and time to appropriate therapy (T3) in age Decile 1 (A), age Decile 2 (B), and age Decile 3 (C). Time is represented in months on the horizontal and axis cumulative incidence function on the vertical axis. In (A) (60- to 70-year-old group), at 36 months, the cumulative incidence function of death with no therapy is ∼0.1 (10%) and the CIF of appropriate therapy is similar, 0.1 (10%). In contrast, in the (C) (>80-year-old group), the CIF of death with no appropriate therapy at 36 months is much greater at ∼0.3 (30%) and the CIF of appropriate therapy is similar to the 60- to 70-year-old group at 0.1 (10%).
