Multivariable analysis of the association between potential predictor variables and microbiological eradication in patients with MRSA bacteremia

VariableValue for the variablea
AOR95% CIP value
Treatment group (Combo vs VAN alone)11.241.72–144.340.010
Vancomycin serum level (mg/liter)b0.930.86–0.980.006
Hemodialysis0.0420.01–0.25<0.001
  • a The adjusted odds ratio (AOR) and 95% confidence interval were derived using Firth's penalized maximum-likelihood bias reduction approach to logistic regression.

  • b One patient in each treatment group did not have a vancomycin serum level documented in the electronic medical record. Both patients experienced microbiological eradication.
