The article, which has 68 citations, did not undergo the usual peer-review and was published as a "Special Communication." However, the journal's editor-in-cheif, Howard Bauchner, senior editors at JAMA reviewed the article's factual claims and brought the article through two sets of revisions over two months. Although President Obama is the only author on the article, he thanks seven staff members of the Executive Office in the "Additional Contributions" section.
