Competing Interests

The governemental bodies (Schweizerische Konferenz der kantonalen Gesundheitsdirektorinnen und-direktoren), non-governemental organizations and charities (the Swiss Paediatric Oncology Group, Kinderkrebshilfe Schweiz, Stiftung für krebskranke Kinder Regio Basiliensis) and commercial funders of the Swiss Childhood Cancer Registry (Novartis Oncology Switzerland, Interpharma, Axa Wintherthur, Glaxo Smithkline, Amgen and Bristol Myers Squibb) support the daily running of the registry and have not had and will not have any role in the design, conduct, interpretation or publication of the Swiss Childhood Cancer Registry itself as well as the related research projects. There are no patents, products in development or marketed products to declare. This does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials.
