Table 2.
Positive predictive value for TIA and aCI.
| TIA | HDs | Total | PPV | Specificity | |
|---|---|---|---|---|---|
| SERPINE1-Ab ≥ 1649 | 57 | 119 | 176 | 32.40% (p < 0.0001) | 57.7% |
| aCI | HDs | Total | PPV | Specificity | |
|---|---|---|---|---|---|
| SERPINE1-Ab ≥ 1857 | 271 | 93 | 364 | 74.50% (p < 0.0001) | 66.9% |
The positive predictive values and specificity for TIA and aCI were calculated using the SERPINE1 cutoff values obtained from the receiver operating characteristic curve analysis.
