Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoints of this clinical investigation are the percentage of CGM-comparator pairs with comparator measurement 300 mg/dl. Here only venous comparator measurements with YSI will be considered. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints of this clinical investigation are a subset of the proposed eCGM accuracy requirements: - For comparator measurements 180 mg/dl, - For comparator measurements >180 mg/dl, the percentage of CGM-comparator pairs with difference within ±15% or ±40% (relative to the comparator value), as well as with CGM values <70 mg/dl. These analyses will be carried out for both YSI and Integra comparator measurements. | — |
