Continuous Glucose Error Grid Analysis (CG-EGA) Results as Obtained by Considering Different Time Lag Compensation Methods
| Glycemic range | CG-EGA summary output | Time Lag compensation method | ||
|---|---|---|---|---|
| Uncompensated data | Method A: application of a fixed delay | Method B: application of a variable delay | ||
| Hypoglycemia (<70 mg/dl; 1.4% of the data) | Accurate readings | 100% | 100% | 100% |
| Benign errors | 0.0% | 0.0% | 0.0% | |
| Significant errors | 0.0% | 0.0% | 0.0% | |
| Euglycemia (70–180 mg/dl; 61.1% of the data) | Accurate readings | 94.5% | 97.2% | 98.3% |
| Benign errors | 5.5% | 2.8% | 1.7% | |
| Significant errors | 0.0% | 0.0% | 0.0% | |
| Hyperglycemia(>180 mg/dl; 37.5% of the data) | Accurate readings | 80.8% | 87.2% | 95.8% |
| Benign errors | 17.9% | 11.5% | 2.8% | |
| Significant errors | 1.3% | 1.3% | 1.4% | |
