Five Glycemic Variability Metrics Applied to Simulated CGM Profiles Using Square Waves with the Same Amplitudes but Different Periods
| Period of oscillation (hours) | GVP (%) | MAG | CONGA1 | CV | SD |
|---|---|---|---|---|---|
| 6 | 95 | 57.9 | 242.81 | 0.8184 | 180.04 |
| 12 | 46 | 27.9 | 264.01 | 0.8184 | 180.04 |
| 28 | 18 | 10.7 | 276.88 | 0.8184 | 180.04 |
| 84 | 4 | 2.1 | 283.49 | 0.8184 | 180.04 |
The results show that three metrics capture the difference in glycemic variability (GVP, MAG, and (CONGA), whereas two others (CV and SD) do not.
CV, coefficient of variation; GVP, glycemic variability percentage; MAG, mean absolute glucose; SD, standard deviation.
