Summary of Findings	Of the 80 systematic reviews of traditional Chinese medicine trials randomly selected from the Cochrane database of systematic reviews, 43 (54%) searched Chinese databases and 37 (46%) did not. 15 (35%) of systematic reviews that searched Chinese databases and 12 (32%) of systematic reviews that did not search Chinese databases drew a conclusion that tended to support the efficacy of traditional Chinese medicine. In addition, 41 of the 43 systematic reviews (95%) that searched Chinese databases had included Chinese co-authors, while only 4 (11%) of the 37 systematic reviews that did not search Chinese databases had Chinese co-authors.
