Kaplan–Meier plots for time to failure are shown for (a) the presence or absence of S. aureus infection, (b) primary versus previously revised implant, (c) arthroscopic versus open debridement and (d) length of intravenous (iv) antibiotic use. The x-axes show days since DAIR and the y-axes show the proportion without treatment failure. The numbers at risk at each timepoint are shown beneath each plot.
