Erratum to: Cancer Causes Control (2012) 23:1297–1305 DOI 10.1007/s10552-012-0007-x

During the work on our project, a small programming error was discovered. A small population of children who were not born in Norway, especially during the first 2 years of the study period (1965–1966) was included in the original manuscript.

All analyses of the published paper were repeated. Fortunately, only small differences in numbers were observed, and all conclusions remained unchanged. The revised Tables 1, 2, 3 and Figs. 1, 2 are presented below.
