Table 3.
Range of behavioral cutoffs for speech fluency and ROC prediction.
| Behavioral measure | Cutoff range | Cluster classification accuracy (%) | AF-LL AUC ROC (%) | AF-LL threshold (cc) |
|---|---|---|---|---|
| CIUs/min | 8–13 | 97.9 | 93.5 | 3.74 |
| 14–18 | 100 | 96.0 | 3.74 | |
| 19–21 | 100 | 95.3 | 3.39 | |
| Words/min | 31–32 | 97.9 | 84.0 | 4.00 |
| 33–35 | 100 | 81.9 | 3.74 | |
| 36–37 | 100 | 90.7 | 4.00 | |
| BNT | 5 | 97.9 | 87.7 | 4.25 |
| 6–7 | 100 | 90.0 | 4.01 | |
| 8 | 95.8 | 91.1 | 3.74 |
Table shows discriminant cluster classification accuracy of all data points, and resulting ROC prediction of AF-LL threshold and AUC. BNT measures are derived from the BNT aphasia Short Form, and maximum score is 15.
