The formulation of inclusive criteria is very important for the quality of systematic reviews as well as the reliability of results. However, among the systematic reviews based on randomized controlled trials (RCTs) published in Chinese periodicals, there are differences existing in the definition of inclusive criteria of RCTs, which may lead to the incomplete or inequitable inclusion. In addition, the relatively lower quality of domestic RCTs may also cause the possibility of bias. In this study, sampling analysis is applied to assess the current situation of both the RCTs definition for inclusive criteria of domestic systematic reviews and the types of practically included RCTs, so as to figure out the existing problems.
