Table 2.
Comparisons of C-indexes of the present risk score with other already available risk scores to predict major adverse cardiovascular events in the evaluation and validation data sets.
| Risk scores | Evaluation cohort | Validation cohort | ||
|---|---|---|---|---|
| C-index | 95%CI | C-index | 95%CI | |
| Apelin-12 based nomogram | 0.758 | 0.707–0.809 | 0.763 | 0.689–0.837 |
| TIMI risk index | 0.625 | 0.568–0.682 | 0.587 | 0.489–0.685 |
| PAMI risk score | 0.652 | 0.593–0.711 | 0.657 | 0.559–0.755 |
| C-ACS risk score | 0.638 | 0.579–0.697 | 0.614 | 0.514–0.714 |
TIMI = thrombolysis in myocardial infarction; PAMI=primary angioplasty in myocardial infarction; C-ACS =Canada acute coronary syndrome; CI = confidence interval.
