Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Overall percentage of sensor values(Metronom sensor) which fall within ± 20 mg/dl of the mean reference values at glucose (Super GL2/YSI). Measurements are performed at every in-house visit(D1, D7, D14, D4/10 of wear time) in 15 minute intervals for up to 8 hours. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Percentage of sensor values which fall within ± 20 mg/dl of the mean reference values at glucose concentrations <100 mg/dl and within ± 20% at glucose concentrations =100 mg/dl on different days of wear-time - Percentage of sensor values which fall within ± 15 mg/dl of the mean reference values at glucose concentrations <100 mg/dl and within ± 15% at glucose concentrations =100 mg/dl (cf. ISO 15197: 2013, Chapter 6.3.3) (overall, on different days of wear-time) - Percentage of sensor values which fall within ± 30 mg/dl of the mean reference values at glucose concentrations <100 mg/dl and within ± 30% at glucose concentrations =100 mg/dl (overall, on different days of wear-time) - Percentage of sensor values which fall within ± 40 mg/dl of the mean reference values at glucose concentrations <100 mg/dl and within ± 40% at glucose concentrations =100 mg/dl (overall, on different days of wear-time) - Overall percentage of test-to-reference measurement pairs with an Absolute Relative Difference (ARD) =15%. - Percentage of test-to-reference measurement pairs with an Absolute Relative Difference (ARD) =15% (overall, on different days of wear-time) - Mean (MARD) and Median Absolute Relative Difference (MedARD) (overall, on different days of wear-time) - Mean (MARD) and Median Absolute Relative Difference (MedARD) with regard to reference measurements in the hypoglycaemic (=70mg/dl), euglycaemic (70-180mg/dl), and hyperglycaemic (=180mg/dl) area (overall, on different days of wear-time) - Bland–Altman analysis comparing sensor values with reference measurements (overall, on different days of wear-time) - Distribution of data points in the Point and Rate Error Grid (overall, on different days of wear-time) | — |
