Table 8 Incidence rate of partial foot and transtibial amputation

From: A systematic review describing incidence rate and prevalence of dysvascular partial foot amputation; how both have changed over time and compare to transtibial amputation

  1. 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
  2. aPFA cohort includes only those with toe amputation
  3. bPFA cohort includes “through foot” level only, excludes persons with only toe amputation
  4. cPFA cohort includes people with toe/TMA amputation
