Overly stringent inclusion criteria affecting external validity
|Number of systematic reviews included
|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.
