In the print version of this article and the version originally published online, Carole Ben-Maimon was incorrectly listed as president and CEO of Barr Pharmaceuticals. She is, in fact, president and COO of Duramed Research, a subsidiary of Barr Pharmaceuticals. Her email address was also incorrect; her correct email address is cbenmaimon@barrlabs.com. The error has been corrected in the PDF version of the article.
