  • For both all-cause mortality and fatal and nonfatal cardiac outcomes, patients were divided according to the occurrence of the event of interest. Patients who died and patients who survived as well as patients with and without fatal and nonfatal cardiac events were divided in three groups according to the predicted probability of the event of interest (<10%, 20%–20%, and >20%) estimated by either a model including standard risk factors (horizontal rows) or a model including the same risk factors and BL-US (vertical rows; more details in Results).
