Note: Percentage is reported in parentheses only for the number of cases with diabetic foot complications.
a
Total sample size = 259 407.
b
Gender variable had 1 missing value, and age variable had 12 missing values.
c
True numbers are not reported due to the confidentiality requirement of the Sax Institute's 45 and Up Study.
d
Neither diabetic peripheral neuropathy nor diabetes‐related foot/toe amputation was found as a cause of death in the RBDM data in 2011, n = number of total cases, m = number of total deaths.
