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]

  1. Rate differences expressed per 100.000 person-years. Confidence intervals (95% CIs) and p values [in brackets] based on cluster-robust bootstrap with 5000 resamples (clustering by region). Estimates reflect the average impact over the full period 2008–2019 and post-intervention phases 2008–2013 and 2014–2019 respectively for the age groups 60–74 years (total study population) and 60–69 years. For the age group 70–74 years; estimates reflect the average impact over the period 2011–2019 (birth cohorts exposed to organised screening entered this age group in 2011, see Supplementary Fig. 1 for details) and post-intervention phases 2011–2013 and 2014–2019 respectively
  2. (1) Difference-in-difference estimations including region and year fixed effects
  3. (2) Difference-in-difference estimations adjusted for age groups (5-year groups), sex, educational attainment (primary, secondary, tertiary), and region of birth (Nordic, non-Western, other Western countries)
  4. aIn-time placebo test by restricting the data to the pre-intervention period and assigning a hypothetical intervention in 2006
