The March 2014 news article 'Competition aims to revive languishing breast cancer inventions' (Nat. Med. 20, 223, 2014) did not specify that the Center for Advancing Innovation coordinated the fundraising effort and inaccurately implied that NCI has 1,800 patented inventions in its portfolio. In fact, some of those inventions are not patent protected. The errors have been corrected in the HTML and PDF versions of the article.
The February 2014 Opinion piece 'Pediatric requirements in Europe stymie help for hemophilia' (Nat. Med. 20, 117, 2014) did not specify the competing financial interests as a result of incomplete processing. The error has been corrected in the HTML and PDF versions of the article.
