: The board of the Danish Cytogenetic Central Registry and the Danish Data Protection Authority approved the project with the registration number 2013-41-2017. Data were accessed using a secure remote access to Statistics Denmark. In order to avoid any possibility of personal identification of cases, Statistics Denmark prohibits specification of the exact number of cases with a given condition if less than four, and we therefore report these as “<4”.
