Kaplan-Meier plot of the mice injected with 32D/Flt3.

The fraction of surviving mice is plotted over the time after injection. All but one mouse injected with ITD1 or ITD2 developed the disease (described in the text and in Figure 5) within 4 to 5 weeks after injection and died. Mice injected with wild-type Flt3 survived without obvious disease until day 77 and day 92, when 2 of 10 mice developed the identical disease and also died.
