When the above article was first published online there was a factual error in the following sentence:
The numbers of cases registered were calculated by each Nordic cancer registry for the period 2009–2013 and then compared with the respective numbers shown in NORDCAN version 7.3 (Cancer Registry of Norway, Oslo, Norway) released in July 2016 [11].
This has now been corrected to read:
The numbers of cases registered were calculated by each Nordic cancer registry for the period 2009–2013 and then compared with the respective numbers shown in NORDCAN version 7.3 (Association of Nordic Cancer Registries) released in July 2016 [11].
There was also a typographical error in the following sentence:
Cancer registries of Norway and Finland have from the beginning of cancer registration recorded a broad staging variable (localized – regional – distant – unknown) that is quite similar in both counties.
This has now been corrected to read:
Cancer registries of Norway and Finland have from the beginning of cancer registration recorded a broad staging variable (localized – regional – distant – unknown) that is quite similar in both countries.
Finally, there was a duplication of a subheading: Data on cancer treatment – routine data and quality registries.
This duplicated sub-heading has now been removed.
Taylor and Francis apologizes for these errors.
