Diabetic patients with foot ulcers and diabetic dialysis
patients did not differ in age (p = 0.3), gender (p = 0.5) or
smoking habits (p = 0.9). Body mass index was higher in
the diabetic patients with foot ulcers (28.1 ±6.2 kg/m2
vs. 26.1 ±5.5 kg/m2
, p = 0.02). These groups also differed
with respect to kidney function, as none of the diabetic
patients with foot ulcers had ESRD, 49 % had normal
serum creatinine levels, and only 21% had diabetic
nephropathy.
