Mean values (SD) indicated. Subjects with diabetes are divided into those with type I and type II diabetes. Clinical biochemistry results are given for glucose (mmol/l) and glycosylated haemoglobin (HbA1c,%). Symbols used indicate results of Mann-Whitney tests, *denotes p⩽0.02 compared to controls and ψ denotes p = 0.003 compared to the NDR group.
