Table 3a. Multivariate analysis of covariates for relapse-free survival.

Parameter	Hazard ratio (95% confidence interval)	P value
At Response (1 – 2 months from Therapy Initiation) (N=166)
Age	1.03 (1.00, 1.07)	0.08
Cyto (Fav vs. others)	0.24 (0.07, 0.81)	0.02
Response (CRi/CRp vs. CR)	2.39 (0.92, 6.24)	0.07
MRD at CR	2.83 (1.31, 6.09)	0.008
During Consolidation (3 – 7 Months from Therapy Initiation) (N=116)
Age	1.00 (0.97, 1.04)	0.82
Cyto (Fav vs. others)	0.46 (0.15, 1.42)	0.17
Response (CRi/CRp vs. CR)	1.28 (0.39, 4.19)	0.68
MRD at 3-7 Months	50.38 (9.18, 276.63)	<0.0001
At Completion of Therapy (≥ 8 Months from Therapy Initiation) (N=69)*
Age	1.00 (0.96, 1.05)	0.91
Cyto (Fav vs. others)	0.98 (0.27, 3.62)	0.98
MRD at ≥ 8 Months	12.98 (3.82, 44.12)	<0.0001

^*The effect of response cannot be estimated because among the 65 evaluable patients, only 1 patient had CRp, the remaining 64 patients all had CR.
