Table 3b. Multivariate Cox regression analysis of covariates for overall survival.

Parameter	Hazard ratio (95% confidence interval)	P value
At Response (1 – 2 months from Therapy Initiation) (N=166)
Age	1.05 (1.00, 1.09)	0.05
Cyto (Fav vs. Others)	0.07 (0.01, 0.57)	0.01
Response (CRi/CRp vs. CR)	1.06 (0.34, 3.30)	0.93
MRD at CR	5.17 (1.98, 13.49)	0.0008
During Consolidation (3 – 7 Months from Therapy Initiation) (N=116)
Age	1.00 (0.96, 1.04)	0.89
Cyto (Fav vs. Others)	0.42 (0.09, 1.97)	0.27
Response (CRi/CRp vs. CR)	0.88 (0.22, 3.46)	0.85
MRD at 3-7 Months	12.57 (3.94, 40.07)	<0.0001
At Completion of Therapy (≥ 8 Months from Therapy Initiation) (N=69)*
Age	1.01 (0.97, 1.06)	0.60
Cyto (Fav vs. Others)	0.91 (0.14, 5.75)	0.92
MRD at ≥ 8 Months	10.19 (2.34, 44.34)	0.002

^*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.
