Shock as a covariate in a study of treatment of methicillin-resistant Staphylococcus aureus bacteremia.

NOTE. Data are summarized from the article by Soriano et al. [1]. NA, receipt of inappropriate empirical therapy; VMIC 1.0, receipt of empirical vancomycin and an isolate with a vancomycin MIC of 1 mg/mL; VMIC 1.5, receipt of empirical vancomycin and an isolate with a vancomycin MIC of 1.5 mg/mL; VMIC 2.0, receipt of empirical vancomycin and an isolate with a vancomycin MIC of 2 mg/mL. dence-rate ratios from this analysis are somewhat closer to those reported for the high-income cohorts in the original analysis [2]. The sensitivity analysis prompted by the letter from Caluwaerts and Colebunders thus strengthens our conclusions that the reduction in rates of TB during the firs year of HAART is similar in lowincome and high-income settings.
