Aim To assess the completeness of search strategies of systematic reviews of acupuncture, an ancient Chinese intervention, published on the Cochrane Collaboration website up to February 2009.
Level of Investigation Descriptive
Summary of Findings Of the 48 completed Cochrane reviews only 13 (27%) of the included reviews and protocols searched Chinese language databases. The majority of the 48 full reviews (n=28), were inconclusive because of a lack of included studies to fully answer the research question. After stratifying on the use of Chinese databases, a greater proportion of the reviews which did not search Chinese databases were inconclusive as to the effectiveness of acupuncture (68.6% compared with 30.8%). 41.5% of the included articles had at least one Chinese speaking author. Two-thirds of the reviews and protocols (n=40) had the capacity or stated that they translated Chinese language abstracts to determine inclusion for the review. However, seven (10.8%) articles had a language restriction on the inclusion criteria and only reviewed English language articles.
