Data collection and storage

Patients are assigned a randomly selected project identification/serial number within each SCI department in Norway. This serial number follows the individual patient through the rest of the project. The serial number and person identification form the key code. The key code and the data set will be stored, locked in different fireproof cabinets, where only the main investigator has access. Data and Telecommunications Authority’s requirements for safe information flow will be followed [25]. Only the main investigator will have access to the final trial data set. This is in line with the ethical approval of the study, given by the National Regional Ethical Committee (NREC) in Norway [17]. The main investigator will terminate the trial in 2019, and the collected results will be terminated in 2024, according to the NREC approval.
