FIGURE 2.
Temporal trends of methicillin-resistant Staphylococcus aureus (MRSA) acquisition at indwelling device sites. Each row corresponds to a different nursing home resident, and each column represents a follow-up visit (in days). White squares correspond to a follow-up day during which residents were not colonized with MRSA at their device insertion site; gray squares correspond to days for which that resident was lost to follow-up. X represents colonization at the enteral feeding tube site, and O represents colonization at the suprapubic urinary catheter site.
