Median residual survival.

Median residual survival time after complete remission (CR) or resistance as functions of the times to these nonfatal events. CR times are indicated along the top of the graph, and declaration of resistance times are indicated along the bottom. Of the 740 patients achieving CR, 19 required ≤20 days, 406 required 21–30 days, 213 required 31–40 days, 65 required 41–50 days, and 37 required >50 days.
