Article

Concussion (Clinical Practice, N Engl J Med 2007:356;166 - 172) . The second sentence of the article (page 166) should have read “This event is so common, affecting about 128 people per 100,000 population in the United States yearly,1 that almost all physicians are called on at some time to provide care at the scene or to treat the sequelae of concussion” rather than “affecting about 50 people per 100,000 population.” The text has been corrected on the Journal's Web site at www.nejm.org.
