Standardized CGM metrics
| 2017 international consensus on CGM metrics (18) |
|---|
| 1. Number of days CGM worn |
| 2. Percentage of time CGM is active |
| 3. Mean glucose |
| 4. Estimated A1C |
| 5. Glycemic variability (%CV or SD) |
| 6. Time >250 mg/dL (>13.9 mmol/L) |
| 7. Time >180 mg/dL (>10.0 mmol/L) |
| 8. Time 70–180 mg/dL (3.9–10.0 mmol/L) |
| 9. Time <70 mg/dL (<3.9 mmol/L) |
| 10. Time <54 mg/dL (<3.0 mmol/L) |
| 11. LBGI and HBGI (risk indices) |
| 12. Episodes (hypoglycemia and hyperglycemia) 15 min |
| 13. Area under the curve |
| 14. Time blocks (24-h, day, night) |
| Use of Ambulatory Glucose Profile (AGP) for CGM report |
CV, coefficient of variation; LBGI, low blood glucose index; HBGI, high blood glucose index.
