Acupuncture and rheumatoid arthritis

Abstract
Sir, While the article by David et al. [1] reflects concerns among many scientific acupuncturists, its research methodology is flawed and contrary to traditional Chinese acupuncture. The paper seems more concerned with statistical rigour than with an adequate understanding of acupuncture in the treatment of rheumatoid arthritis (RA). This letter deals with specific aspects of acupuncture methodology and includes some general comments.
