Multivariate analysis of parameters with P<0.1 in early death in 15 days after treatment

Parameters	Beta value	Odds ratio (95% confidence interval)	P value
WBC at diagnosis	0.000	1.000 (1.000-1.000)	0.271
ECOG performance score	0.959	2.609 (1.708-3.985)	<0.001
Charlson Score below 6*	-0.734	0.480 (0.115-2.003)	0.314
APL type AML**	2.993	19.953 (1.972-201.910)	0.011
Non-APL type AML**	1.635	5.128 (0.705-37.294)	0.106
Non-intensive treatment***	1.487	4.423 (1.106-17.686)	0.036

Note: Univariate comparisons with a P value <0.1 were included in multivariate analyses in which statistical significance threshold was accepted as P<0.05. Logistic regression analysis was used to study simultaneous effect of selected variables.

^*Charlson Score 6 and above was the reference group.

^**Secondary type disease was the reference group.

^***Intensive treatment was the reference group.
