PFA Incidence rate includes data for toe amputation (3.4) and “foot” amputation (0.3); NR not reported. Unable to be calculated because there was no annual incidence rate data over time reported in the article
^aPFA cohort includes only those with toe amputation
^bPFA cohort includes “through foot” level only, excludes persons with only toe amputation
^cPFA cohort includes people with toe/TMA amputation
