Erratum: Prevalence of Chronic Obstructive Pulmonary Disease in China

There was an omission in the article "Prevalence of Chronic Obstructive Pulmonary Disease in China: A Large, Population-based Survey," which appeared in the October 15 issue of AJRCCM (1). Because of a production error, the sentence "All authors contributed equally to this study" was inadvertently deleted. This sentence should have appeared as footnote on the first page of the article.
