Also in the Seattle study, 67 people with diabetes presenting for initial non-traumaticamputation between 1984 and 1987 were compared with 236 consecutive people withdiabetes seen for other unrelated surgery (del Aguila et al, 1994). There was nosignificant difference between the case or control groups in age (63.6 v 16.1 years) orduration of diabetes (12.4 v 10.9 years). Presence of prior foot ulcer wasindependently associated with risk of lower extremity amputation (OR 10.9, CI 4.6-25.5).
