Comparison of the prevalence of body sites positive for S. aureus or Gram-negative rod (GNR) after decolonization with intranasal mupirocin and topical chlorhexidine

PR= prevalence ratio
Indicates the number of weeks after decolonization that the samples were obtained. For example, at 1 week post decolonization the samples collected at the Week 5 study visit were compared to the samples collected at the Week 4 study visit. The Week 4 study visit occurred immediately before decolonization. The Week 5 study visit occurred very soon after decolonization.
