aPatients with unknown Gleason Score were classified as high risk, if any high risk criteria were met (e.g. patients with PSA > 20 ng/ml were considered as high risk, even in case of unknown Gleason Score)
bCardiovascular includes: Myocardial infarction, stroke, cerebral hemorrhage in a Marcumar patient, ruptured aortic aneurism, and cardiac arrest in coronary heart disease
cInfection includes pneumonia and sepsis
