Fig 5. Comparison of the biofilm-forming capacity of S. aureus isolates from prosthetic joint infection (PJI) and uninfected prosthetic joint (PJU) groups.

Values were calculated as percentage capacity to form biofilms relative to S. aureus control strain UAMS-1. Box ends represent the 25^th and 75^th percentiles, and whisker ends represent the minimum and maximum. There was no difference in biofilm-forming capacity between isolates in the PJI and PJU groups.
