Declarations
:
: In Sweden, informed consent is not required in order to be part of a national registry such as the one we have used in the present study. This is clearly stated in Swedish law. The following paragraphs underline this fact. (Chapter 7 of the Swedish Patient Data Act (2008:355)). This is also part of the ethical approval for the present study which has been approved by the Swedish ethical review authority so thereby the waiving of the consent is also approved by the Swedish ethical review authority. The present study was approved by Gothenburg Ethical Committee on 28 November 2018 (Dnr: 825-18). All patients who are registered in the SFR receive according to Swedish legislation information about their registration and are given the option of withdrawing (opt-out). Written consent is not needed for registering patients in national quality registers in Sweden. The data from SFR were fully anonymised before data analysis begun. The study was approved by Ethical Committee confirming that all methods were carried out in accordance with relevant guidelines and regulations.
