In the version of this article initially published online the legend of Figure 1 should read “The 5th edition of the UICC TNM system was used to classify patients. We performed a visual, illustrative comparison using data on expected survival on the basis of group composition regarding age and sex for each stage group. These data were obtained from the German Federal Bureau of Statistics (Bundesamt für Statistik). No further statistical analysis was performed, as the visual illustration of the good prognosis of patients with differentiated thyroid cancer was the only goal of this figure.” The error has been corrected for the HTML and PDF versions of the article.
