Receiver operating characteristic (ROC) areas (C indices) of placebo patients with complete records (n=1998). Nine-year risks assigned by the Cox analysis using all standard predictors
| Outcome | Ordinary ROC area (event Yes compared with No, regardless of time) | DynamicCindex* |
| Acute myocardial infarction (AMI) | 0.643 | 0.651 |
| Unstable angina pectoris (UAP) | 0.637 | 0.616 |
| Cerebrovascular disease (CVD) | 0.606 | 0.680 |
| Cardiovascular death (non-cardiovascular death) | 0.761 (0.736) | 0.730 (0.728) |
| All-cause death | 0.792 | 0.737 |
| Composite outcome† | 0.711 | 0.640 |
*When a patient had no event of the kind concerned within the 9-year window, we define: toe (time of event) = + ∞. Then, C is the frequency of concordant risks (equal risk weighs 1/2) among patient pairs whose toe data allow us to decide who died first: C=freq {concordant risks (or equal risk, 0.5) | sign of toe difference known from data}.
†Consists of acute myocardial infarction, unstable angina pectoris, cerebrovascular disease and all-cause death.
