Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Diagnostic accuracy of novel and existing circulating biomarkers for sight threatening retinopathy; the sensitivity, specificity and receiver operating characteristics (ROC) curves will be reported. As it is a cross-sectional study, there is a one-off blood collection, analysis and reporting. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Diagnostic accuracy of novel and existing circulating biomarkers for any diabetic retinopathy 2. Diagnostic accuracy of novel and existing circulating biomarkers for identifying people at risk of microvascular and/or macrovascular complications of diabetes The sensitivity, specificity and receiver operating characteristics (ROC) curves will be reported. As it is a cross-sectional study, there is a one-off blood collection, analysis and reporting. | — |
