Assessing the risk of bias of quantitative analytical studies: introducing the vision for critical appraisal within JBI systematic reviews

A key step in the systematic review process is the assessment of the methodological quality (or risk of bias) of the included studies. At JBI, we have developed several tools to assist with this evaluation. As evidence synthesis methods continue to evolve, it has been necessary to revise and reflect on JBI's current approach to critical appraisal and to plan a strategy for the future. In this first paper of a series focusing on risk of bias assessment, we introduce our vision for risk of bias assessment for JBI. In future papers in this series, the methodological approach taken for this revision process will be discussed, along with the revised tools and guidance for using these tools.
