In Finland, Finnish Institute for Health and Welfare can give a permission to data processing in the registry-based data. Because we had received permission, individual inform consent was not required. For this study, we received research permission to data processing from Finnish Institute for Health and Welfare (THL/439/5.05.00/2018) and ethical permission from the Human Sciences Ethics Committee of the Helsinki Region Universities of Applied Sciences (2/2018).
