Multivariate Analysis for EFS

Parameter	Multivariate Analysis
Parameter	HR	95% CI	P
LCP (vs ECP)	2.05	1.49–2.83	<.0001
BM blasts	1.09	1.01–1.16	.013
Baseline percentage Ph1+ cells in BM	1.01	1.00–1.02	.011
High Sokal score (vs low/int score)	2.38	1.39–4.05	.001
Grade 3–4 anemia (yes vs no)	1.72	1.14–2.60	.009

EFS indicates event-free survival; HR, hazard ratio; CI, confidence interval; LCP, late chronic phase; ECP, early chronic phase; BM, bone marrow; Ph1+, Philadelphia chromosome positive; int, intermediate.
