Table 3.
AUCs for the three FCSRT ISDA indexes (encoding, consolidation, and retrieval) and 95% confidence intervals
| ISDA indexes and types of recall | AUC | 95% confidence intervals |
|
|---|---|---|---|
| Inferior | Superior | ||
| Encoding Index | .97 | .93 | 1.01 |
| Consolidation Index | .79 | .67 | .91 |
| Retrieval Index | .56 | .40 | .72 |
| Immediate free recall | .98 | .95 | 1 |
| Immediate cued recall | .81 | .70 | .92 |
| Total immediate recall | .97 | .93 | 1 |
| Delayed free recall | .98 | .95 | 1 |
| Delayed cued recall | .66 | .51 | .81 |
| Total delayed recall | .96 | .92 | 1 |
Abbreviations: aMCI, amnestic mild cognitive impairment; AUC, area under the curve; FCSRT, Free and Cued Selective Reminding Test; ISDA, item-specific deficit approach.
NOTE. The results show great AUC for most measures except for the Retrieval Index and delayed cued recall that seem to discriminate less well between patients with aMCI and controls.
