Variables	Relative risk (95% CI)	P
Blasts in bone marrow before transplantation^4-150
(1) Less than 5%	1.00	P^‡_overall < .0001
(2) 5%-20%	2.9 (1.7-4.9)	P₁₂ < .0001
(3) More than 20%	6.3 (3.4-11.6)	P₁₃ < .0001
(4) Unknown	2.5 (1.3-4.9)	P₁₄₀ = .0082
IPSS at diagnosis^4-153
(1) High risk	1.00
(2) Intermediate/low risk	0.5 (0.3-0.8)	P₁₂ = .0061
(3) Unknown	0.4 (0.2-0.7)	P₁₃ = .0033
GVHD prophylaxis
(1) Non T-cell depletion	1.00
(2) T-cell depletion	1.8 (1.0-3.2)	P = .0361

3 df.

P of intermediate versus low IPSS score at diagnosis: .1699.

P₁₂ = probability of testing (1) = (2); P₁₃ = probability of testing (1) = (3); P₁₄ = probability of testing (1) = (4).
