: In this study, initiated over 50 years ago, participant consent was considered implicit on attending the screening investigation, written consent was not a requirement from the ethics committee, and the subsequent interventions were carried out as part of clinical management of high risk individuals. The men in the control group were never contacted, only followed through local and national registries [CitationRef removed]. However, the process of running the data file of the participants against the Swedish National Patient Registry and the Swedish Cause of Death Registry was approved by the Ethical Committee at the University of Gothenburg (886-13, T187-16). The study complied with the Declaration of Helsinki issued 1974.
