Multivariate Logistic Regression Model^*

Variable	Risk of Bleeding	P Value (Univariate Analysis)	P Value (Multivariate Analysis)	Risk Ratio
Anemia, g/dL^†	Higher	.007	NS
Thrombocytopenia, ×10⁹/L	Higher	.001	.02	1.002
PB blast %, higher	Higher	.049	NS
BM blast %, higher	Higher	.002	NS
Longer CML duration	Higher	.049	NS
CML phase: AP/BP (vs CP)	Higher	.002	.03	1.69
Prior IFN-α (yes)	Higher	.08	NS

NS indicates not significant; PB, peripheral blood; BM, bone marrow; CML, chronic myelogenous leukemia; AP, accelerated phase; BP, blast phase; CP, chronic phase; IFN-α, interferon-α.

Estimation of the association between disease and patient characteristics and the development of bleeding, considering other covariates in the model.

Anemia denotes a hemoglobin level <10 g/dL.
