The Renal Insufficiency And Cardiovascular Events (RIACE) Italian multicentre study Summary of results and conclusions • A single UAE value, thought to be encumbered with high intra-individual variability, is an accurate predictor of the stage of nephropathy in subjects with type 2 diabetes. • Multiple UAE measurements may not be necessary for classification purposes in both clinical and epidemiological settings.
