Table 1 Comparisons of patient characteristics between infection and non-infection groups based on the modified MSIS criteria

From: Can we rely on the combination of serological tests and frozen sections at the time of reimplantation for two-stage exchange hip arthroplasty in patients with a “dry tap”?
