Independent determinant factors for VC by multiple regression analysis in hemodialysis patients.

Variables	B	p Value	Exp(B)/OR	95% CI for Exp(B)
HD vintage (months)	0.022	0.010	1.022	1.005–1.039
Age (years)	0.073	0.006	1.075	1.021–1.132
Escherichia-Shigella	0.0003	0.081	1.000	1.000–1.001
Ruminococcus	−0.001	0.027	0.999	0.997–1.000
Constant	−5.007	0.003	0.007	–

VC: vascular calcification; B: coefficient; OR: odds ratio; CI: confidence interval; HD: hemodialysis.

Age, HD vintage, serum creatinine, Escherichia-Shigella, and Ruminococcus were initially included in the multivariate logistic regression model to determine the independent influencing factors of VC (using backward conditional).
