The second study objective compared the HRQOL in
three groups of diabetes patients: the group of 78 dialysis
patients with diabetes, a group of 127 diabetes patients
with foot ulcers on or below the malleoli, taken from an
anonymised database of patients treated at outpatient
clinics in the Oslo area [16], and a group of 221 diabetes
patients without complications, who had participated in
the Norwegian Survey of Level of Living in 2002.
