In Table 2 of this article, the footnote was missing and should have read ‘Over the period 2003–2006, data on colon cancers have been complemented from the Cancer Registry due to lack of registration of colon cancers in the Swedish Colorectal Cancer Registry (SCRCR) over the period’.

In Table 3 of this article, the ‘Screening roll-out’ data in the column ‘70–74 years’ was incorrectly published with – 9.03 (− 29.88, 11.81), − 8.83 (− 29.43, 11.77) [0.401] [0.396] and should have been − 15.40 (− 36.28, 5.49) [0.148], − 14.96 (− 35.59, 5.66) [0.155]
