Association between Accessory Gene Regulator Polymorphism and Mortality among Critically Ill Patients Receiving Vancomycin for Nosocomial MRSA Bacteremia: A Cohort Study

Table 3

Multivariate Cox regression analysis of factors associated with in-hospital mortality in critically ill patients with MRSA bacteremia treated with vancomycin.

Variable	Adjusted HR	95% CI	P value
Initial plasma CRP, mg/L	1.01	1.002–1.019	0.01
Initial serum creatinine, g/dL	2.11	1.21–3.68	0.008
Group II agr specificity	12.60	2.07–76.69	0.006

Note. HR: hazard ratio; 95% CI: 95% confidence interval; CRP: C-reactive protein; agr: accessory gene regulator.
