Defined in DCCT by the presence of definite clinically evident distal symmetrical polyneuropathy and an abnormal nerve conduction study or in EDIC by MNSI >6 positive responses on the questionnaire or a score >2 on the examination.
DCCT = Diabetes Control and Complications Trial; EDIC = Epidemiology of Diabetes Intervention and Complication; ETDRS = Early Treatment Diabetic Retinopathy Study; MNSI = Michigan Neuropathy Screening Index.
