Factors predicting sensitivity to Vancomycin according to logistic regression analysis

	B	SE	Wald	P	OR	95% CI
PDAP-cloudy group (with PDAP-multi group as reference)	3.321	1.102	9.075	0.003	27.678	3.191-240.103
Residual renal Ccr	-0.045	0.020	4.885	0.027	0.956	0.918–0.995
Every increase of 100/µL WBC in peritoneal fluid	-0.012	0.004	8.274	0.004	0.988	0.980–0.996
First episode peritonitis (Yes)	-0.806	0.392	4.240	0.039	0.447	0.207–0.962
Diabetes (Yes)	1.294	0.427	9.192	0.002	3.646	1.580–8.416
Constant	0.811	0.377	4.637	0.031	2.251

Clinical indicator that significantly different (p < 0.1) in comparison between patients with vancomycin sensitive or resistance PDAP group were selected in logistic regression model including PDAP cloudy group, WBC count in the peritoneal effluent, diabetes and first episode peritonitis, residual renal creatinine clearance and dialysis vintage The conditional forward method was used for final model factor selection

Abbreviation: PDAP, peritoneal dialysis-associated peritonitis; WBC, white blood cell; Ccr, creatinine clearance
