  1. Characteristics and co-diagnoses of Rutherford grade 5 and Rutherford grade 6 patients with and without diabetes (DM+/DM−). Data are given as patient numbers and percentages related to the respective subgroup. Statistical significance was tested via contingency table, p values <0.05 are considered significant
  2. Italic values are statistically significant
  3. DM diabetes mellitus; CKD chronic kidney disease; CAD coronary artery disease; CHF chronic heart failure
