  1. Bolded pairs achieved statistical significance (p < 0.05) in chi-square analysis.
  2. MSSA = methicillin-sensitive S. aureus; MRSA = methicillin-resistant S. aureus; TMP/SMX = Trimethoprim/Sulfamethoxazole; NR = Not Reported
  3. aOxacillin resistance defines MRSA vs. MSSA in this clinical laboratory.
