In the version of this article originally published, several competing interests for Erika von Mutius were missing. This sentence was added to the competing interests section: “E.v.M. is an inventor on the patents EP1637147, EP1964570, LU101064 and EP1411977; E.v.M. is an inventor on and has received royalties from the patent EP2361632.” The error has been corrected in the HTML and PDF versions of this article.
