  • 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.
