As the Wagner (W) grades increased, nutritional status, severity of infection and outcome deteriorated. (A) Nutritional status in patients with ulcers of Wagner grades 0–5. The prevalence of malnutrition was 62.0% in patients with foot ulcers. (B) Severity of infection in patients with ulcers of Wagner grades 1–5. Infection was identified in 83.9% of the DFU patients. (C) Outcome of patients with ulcers of Wagner grades 1–5. Only a small proportion of patients with ulcers of Wagner grades 1–4 did not heal well, while the outcome of patients with grade 5 ulcers was poor. (A–C) P<0.001 for the χ² analysis across all groups. DFU, diabetic foot ulcer.
