  • ROBIS: A New Tool to Assess Risk of Bias in Systematic Reviews

    Currently there is no tool designed specifically to assess the risk of bias in the design, conduct or analysis of systematic reviews. ROBIS (Risk Of Bias In Systematic reviews), which was developed lately, aims mainly to assess the risk of bias in the conduct and result interpretation of systematic reviews relating to interventions, etiology, diagnosis and prognosis, as well as the relevance of the systematic review questions and the practice questions that their users want to address. This paper aims to introduce the ROBIS tool to Chinese systematic review developers, guideline developers and other researchers to promote the comprehension of it and its application, so as to improve the quality of systematic reviews in China.

  • Interpretation of ROBIS Tool in Evaluating the Risk of Bias of a Selected Systematic Review

    ObjectiveTo interpret ROBIS, a new tool to evaluate the risk of bias in systematic reviews, to promote the comprehension of it and its proper application. MethodsWe explained each item of ROBIS tool, used it to evaluate the risk of bias of a selected intervention review whose title was Cyclophosphamide for Primary Nephrotic Syndrome of Children: A Systematic Review, and judged the risk of bias in the review. ResultsThe selected systematic review as a whole was rated as “high risk of bias”, because there existed high risk of bias in domain 2 to 4, namely identification and selection of studies, data collection and study appraisal, synthesis and findings. The risk of bias in domain 1 (study eligibility criteria) was low. The relevance of identified studies and the review’s research question was appropriately considered and the reviewers avoided emphasizing results on the basis of their statistical significance. ConclusionROBIS is a new tool worthy of being recommended to evaluate risk of bias in systematic reviews. Reviewers should use ROBIS items as standards to conduct and produce high quality systematic reviews.
