Competing interests
: The authors declare that they have no financial or other relationships that might lead to a conflict of interest. However, co-authors TKG and JSS have received funding from the Research Council of Norway (governmental agency) in the form of an industry-collaborative grant to the Cancer Registry of Norway (governmental agency) in 2019, in order to establish an enlarged cohort of offshore petroleum workers. A condition pertaining to such industry-collaborative grants is that 20% (USD 175,000) of the grant was provided by the petroleum industry and 80% (USD 700,000) from State funding by the Research Council itself with the intention of joining forces for the common interest of occupational health among petroleum workers. The application process was governed by the Research Council alone without any involvement from the industry. The grant does not cover the salary of the PIs or any of the employees at collaborating institutions.
: All cohort members provided informed consent for participation in the study. Necessary legal and ethical approvals were obtained from the Regional Committee for Medical Research Ethics (2018/1162), the Norwegian Data Inspectorate and the Norwegian Directorate of Health. The linkage key for the 11-digit PINs was stored and governed by a third party unavailable to the research team. All data management and analyses were conducted on data with no individual person identified. All results are distributed on a group level, without any possibilities for individual identification.
