Of the 671 primary studies included, less than twenty percent of studies used adequate sequence generation, and only seven percent used adequate allocation concealment. Because of the poor methodological quality of primary studies, nearly half of reviews were reported as being inconclusive, while 27 reviews provided preliminary evidence of CHM's benefits to certain conditions, which should be considered tentative and need to be confirmed with rigorous RCTs. The Chinese government has been aware of the importance of conducting scientifically sound RCTs and has made substantial investments into funding clinical researches of CHM, now many well-designed RCTs of CHM with rigorous methodology are in progress or have been completed in China [74] , we believe future updates of currently inconclusive Cochrane reviews of CHM may reach more definitive conclusions.
