The study design, including information on included data sources (PAS, SHPR, Statistics Sweden) from different data holders were summarized in a study protocol which was approved by the regional ethical committee at Karolinska Institutet, Stockholm (Dnr 2017/746–31/5). Each data holder approved use of data for the study (approval communicated by Tobias Dahlström for Dalarna, Sven-Arne Åsman for Uppsala, Anna Stålhammar for Region Skåne and Marie Röllgårdh for VGR).All data with personal identification number was sent by each data holder to Statistics Sweden for data linkage. To protect the identity of subjects in the database, the personal identification number was replaced by an anonymized code by Statistics Sweden and the research group did not have access to the subjects’ personal identification numbers.
