Quality Assurance

Quality Assurance

The aim is to do quality test analyses and correct observed shortcomings in the NorTwinCan data.

A scientific article will be produced with the following issues included:

  1. good descriptions (background, organization, size, administrative aspects, contact info etc.) of the participating Twin Registers in Denmark, Finland, Norway and Sweden,
  2. quality evaluations (accuracy of linkage keys, completeness of follow-up for vital status, etc.),
  3. numbers of various cancers cases found among persons in the Twin Registers before and after baseline + estimates of annual addition,
  4. estimate population representativeness in the Twin Registers indirectly on the basis of SIR estimates (observed numbers of cancer vs. numbers expected; reference national general population); if some direct comparisons of socio-economic or life habits characters between the Twin Register cohorts and general populations are available, these data should also be utilized.
