Diagnostic performance parameters for cs-cTnI cut off thresholds for mortality
| Cohort | Cs-cTnI threshold relative to ULN | Sensitivity | Specificity | Positive predictive value | Negative predictive value |
|---|---|---|---|---|---|
| Whole population | >ULN | 48.0% | 92.5% | 13.7% | 98.4% |
| >10 × ULN | 13.3% | 98.9% | 24.7% | 97.7% | |
| Study requested cohort | >ULN | 44.4% | 93.6% | 16.7% | 98.3% |
| >10 × ULN | 9.4% | 99.3% | 27.5% | 97.4% |
Cs-cTnI = contemporary sensitivity troponin I; ULN = upper limit of normal.
