Parameter	Simple univariate regression, hazard ratio (95% CI)	p value	Multiple univariate regression, hazard ratio (95% CI)	p value
Male sex	1.31 (0.94–1.82)	0.11	1.34 (0.96–1.87)	0.08
Internal jugular vein	0.53 (0.20–1.43)	0.21
Non-antimicrobial coated CVC	3.26 (1.04–10.23)	0.043	2.94 (0.94–9.25)	0.06
Non-CHG-coated CVC dressing	1.31 (0.91–1.87)	0.15
Complicated CVC insertion	1.41 (0.48–2.54)	0.26
Neutropenia	11.36 (7.06–18.26)	<0.001	11.92 (7.41–19.71)	<0.001

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