After publication of this article [1], the authors reported that in the Results section, in the sentence “The in-hospital mortality for patients with CD decreased from 12.5% in 1986–1990 to 1.8% in 2011–2015”, the mortality in 2011–2015 was actually 0% rather than 1.8%.

The original article [1] has been updated.
