偏倚风险评估系列:(四)整群设计随机对照试验

摘要

This paper introduced the Revised Cochrane Risk of Bias Tool RoB2.0 for cluster-randomized control trials (CRCT) and compared RoB2.0 of CRCT with individually randomized,parallel group trials,and illustrated the application of RoB2.0 for CRCT in a published CRCT.Special signal questions were designed for CRCT according to its specialty that different from individually randomized,parallel group trials in RoB2.0 and also providing information on risk of bias about CRCT in systematic reviews for the synthesis of evidence.%介绍整群设计随机对照试验Cochrane偏倚评估工具2.0版本(RoB2.0)的主要内容,阐述与平行设计RoB2.0的不同之处,并举例说明整群设计RoB2.0的使用方法和注意事项.RoB2.0针对整群设计的自身特点,设置了相应的信号问题,为将整群设计试验纳入系统综述进行证据整合提供偏倚风险信息.
