Data will be handled according to the National Data Protection Agency. All original records (including consent forms and questionnaires) will be archived at the trial site for 15 years. The National Data Protection Agency has approved the biobank (RH-2016- 199). Data checks have been programmed into the data registry to warn when input variables are outside of predefined possible clinical range. All registry data will be compared to external data sources, i.e. medical records, to ensure accuracy. Standard Operating Procedures have been implemented regarding data collection. Patients with missing data for calculating for example SAPS II scores etc. will be excluded from the study.
