Kaplan-Meier plot of probability of achieving CR (A) and CR + PR (B) for TX1 and TX2.

The time, in months, is calculated from the date of the (first) transplant. CD 34+-selected transplants were pooled together with unmanipulated autografts. Disease complete response is significantly correlated with TX2 (see text). One single patient (TX2) reached CR after 32 months from transplant after α IFN treatment.
