Performance of the ERICA score and CBF of PCG + PC in predicting HC, MCI, and AD
| Parameters | HC (Mean) | MCI (Mean) | AD (Mean) | Predicted Probability of Diagnosis (Area under the Curve of ROC) with P Values in Parentheses | ||
|---|---|---|---|---|---|---|
| MCI vs HC | AD vs HC | AD vs MCI | ||||
| ERICA (0–3) | 0.71 ± 0.46 | 0.90 ± 0.64 | 2.15 ± 0.83 | 0.571 (.493) | 0.887 (<.001) | 0.838 (<.001) |
| CBF in PCG + PC (mL/100 g/min) | 46.64 ± 8.4 | 39.08 ± 6.6 | 36.51 ± 8.4 | 0.776 (.002) | 0.810 (<.001) | 0.589 (.339) |
| Combined ERICA and CBF | 0.781 (.002) | 0.957 (<.001) | 0.829 (<.001) | |||
