Results of the multivariate logistic regression analysis on the impact of the anti-infective strategies (I)–(III) on the detection of vancomycin-resistant Enterococcus faecium (VRE).

Variable	Detection of VRE
	OR (95% CI)	p-Value
Antibiotic prophylaxis (vs. G-CSF support)	17.38 (2.24–134.68)	0.01
No prophylaxis (vs. G-CSF support)	10.75 (1.12–103.43)	0.04
Age (per ten years)	1.53 (0.68–3.44)	0.30
ASCT at relapse (vs. first-line treatment)	2.79 (0.62–12.51)	0.18
≥VGPR before ASCT (vs. ≤PR)	2.12 (0.58–7.83)	0.26
Stem cell amount ≥ 2.5 * (vs. <2.5)	0.46 (0.11–1.99)	0.30

Abbreviations: ASCT, autologous stem cell transplantation; CI, confidence interval; OR; Odds Ratio; VGPR, very good partial remission; * ≥2.5 × 10⁶ CD34⁺ cells per kg of body weight.
