Prognostic value of a plasma protein-based biomarker test for chronic kidney disease complicating diabetes in Aboriginal Australians

The predictive value of Promarker^®D tests for incident diabetic kidney disease or rapid decline in estimated glomerular filtration rate was evaluated in 1010 non-Aboriginal and 71 Aboriginal adults with diabetes. Areas under the receiver operating characteristic curves were not significantly different (P ≥ 0.081) for first- (non-Aboriginals 0.890 (95% confidence interval 0.864 to 0.915) and Aboriginals 0.769 (0.624 to 0.915)) and second-generation (0.890 (0.862 to 0.917) and 0.711 (0.543 to 0.878)) tests. Promarker^®D has potential renal prognostic value in Aboriginals with diabetes.
