Male sex	1.50 (1.17–1.93)	0.002	1.53 (1.19–1.96)	0.001
Internal jugular vein	0.62 (0.28–1.40)	0.25
Non-antimicrobial coated CVC	2.14 (1.06–4.33)	0.03	1.95 (0.62–3.94)	0.06
Non-CHG-coated CVC dressing	1.06 (0.82–1.38)	0.65
Complicated CVC insertion	1.40 (0.90–2.19)	0.14
Neutropenia	15.19 (10.24–22.53)	<0.001	15.18 (10.23–22.53)	<0.001

CVC, central venous catheter; CHG, chlorhexidine gluconate gel pad; dCRBSI, definite plus probable central venous catheter-related bloodstream infection; PSM, propensity score matching; 95% CI, 95% confidence interval.
