Odds Ratios for Predictors of Treatment Failure

Predictors	Odds Ratios (95% CI)	p
Hematological malignancies *	4.63 (1.45 – 14.79)	0.01
Charlson score ≤ 4	4.30 (1.34 – 13.76)	0.01

CI, confidence interval;

* The only independent predictor remained in the final logistic regression model using stepwise selection procedure, while the baseline model including hematological malignancies, Charlson score ≤ 4
