Overview of clinical parameters associated to the diabetic patients of each cluster (based on kmeans clustering considering data of both groups).

p value following Bonferroni correction = 0.05/26 = 0.002, *Pairwise Fisher exact test for number of diabetic feet: cluster 2 and 3 significantly different, **Pairwise Fisher exact test for feet men/women: cluster 2 significant different from 3 and 4, FDS: Foot Deformity Score: 6 point scale (1 point for each characteristic: small muscle wasting, bony prominence, prominent metatarsal heads, hammer/claw toes, limited joint mobility, charcot foot deformity). (Charcot foot was an exclusion criteria for this study, limited joint mobility not considered here (prayer sign)). Pedal pulses: palpation of the dorsalis pedis and tibial pulses. Sens Monofil 10 g: sensation of the 10 g monofilament (6 point scale per foot). Risk classification based on Belgian guidelines: risk category 3 = Diabetic patient with at least one of the following complications: history of ulceration/peripheral arterial disease, risk category 2b: = diabetic patient with neuropathy and pronounced rigid foot deformities, risk category 2a = diabetic patient with neuropathy and mild/flexible foot deformities, risk category 1 = diabetic patient with neuropathy, risk 0 = diabetic patient without complications as mentioned in other risk categories.
