Figure 3 Incidence of cardiac death or myocardial infarction (MI) during 3-year follow-up according to the number of cardiac risk factors (left) and allocated strategy in patients with 1 or 2 cardiac risk factors only (right). The incidence of cardiac death or MI was associated with the number of cardiac risk factors at screening (log-rank p < 0.001). There was no significant difference in the long-term incidence of cardiac events between patients allocated to cardiac testing or no testing (log-rank p = 0.30).
