Information available for 95-100% of patients except HLA I and II combined (for 76%), CMV status (for 83-90%), and Karnofsky index, body mass index, and hematological response at or within 6 weeks before BMT (for 85, 79, and 69% of patients, respectively).
At the time, or within 6 weeks, of BMT.
No significant influence on survival time as assessed by log-rank test and Kaplan-Meier survival estimation or by Cox regression analysis.
P values of >.1 were designated NS (not significant).
Test not possible, only patients without T-cell depletion, or with CSA, respectively.
