Table 3 Prevalence of wound severity by ulcer grade and stage (modified University of Texas wound classification system) at admission to the clinics (A), discharge from the clinics (B) of the patients with diabetic foot treated by the structured health care program and subjects with diabetic foot treated by standard care (controls) and 2 year follow-up investigation of the structured health care group alone (C) (SHC n= 684, controls n= 508)

From: Structured health care for subjects with diabetic foot ulcers results in a reduction of major amputation rates
