  • * Since only a few studies provided numbers separately for knee and hip arthroplasty, the mortality rates may not reflect overall rates, these studies being a subset of all studies included.

  • ** One study could provide data for more than 1 group.

  • All-comers included studies where all patients were included and those in which there was no clear description of included patients.

  • †† Revision numbers were often a subset of the mortality for the entire sample, frequently with primary arthroplasty constituting a large majority of cohort and high proportion of all deaths.
