Do Culture-Negative Periprosthetic Joint Infections Have a Worse Outcome Than Culture-Positive Periprosthetic Joint Infections? A Systematic Review and Meta-Analysis

Figure 3

Rates of incidence for culture-negative periprosthetic joint infections of the hip and the knee. Summary estimates for the incidence of CN PJI were calculated using random-effects models with 95% confidence interval (CI). An I² value (statistical heterogeneity) of 0.00% indicates a low variability in intrastudy differences in the overall effect size.
