During almost 20 years, as one of the most important parts of evidence-based IM, systematic review(SR)/meta-analysis(MA) of IM have shown a good development momentum in the aspects of quantity, depth, breadth and influence, but also face the harsh situation of the uncontrolled quantity and quality, especially for SRs in Chinese. Therefore, how to supervise and standardize this area effectively becomes a problem to be solved. Based on the experience both at home and abroad, the authors put forward several kinds of solutions for laying the foundation for further development such as promoting the registration system of SR/MA of IM, effectively setting up the regulatory platform of quality and quantity, launching professional training for SR/MA reviewers, formingqualification registration, developing the data transfer and sharing platform to realize the transparency of evidence process.展开更多
