PFS according to race/haplotype frequency/disease status at the time of MUD search. C + C+ R/ND = white, common haplotype, and remission/newly diagnosed; C + C + PIF/R/R = white, common haplotype, and PIF/relapsed/refractory; C + U + R/ND = white, uncommon haplotype, remission/newly diagnosed; C + U + PIF/R/R = white, uncommon haplotype, and PIF/relapsed/refractory; O + C + R/ND = other race, common haplotype, and remission/newly diagnosed; O + C + PIF/R/R = other race, common haplotype, and PIF/relapsed/refractory; O + U + R/ND = other race, uncommon haplotype, remission/newly diagnosed; O + U + PIF/R/R = other race, uncommon haplotype, and PIF/relapsed/refractory.
