Survival of the 354 patients eligible for transplantation and genetically randomized according to risk profile. (A) Low-risk and (B) non–low-risk patients. The survival times of patients who received an unrelated transplant in first chronic phase were censored at the day of transplantation. The survival differences in the low-risk group were significant for the entire period and for the time until the curves converge (first cut point at year 8) (Wilcoxon-Gehan test: P = .032 and P = .027, respectively). For patients at risk, see Table 2. m.s. indicates median survival. The error bars indicate 95% confidence intervals.¹⁶
