This paper introduces the main contents of ROB-ME (Risk Of Bias due to Missing Evidence), including backgrounds, scope of the tool, signal questions and the operation process. The ROB-ME tool has the advantages of clear logic, complete details, simple operation and good applicability. The ROB-ME tool offers considerable advantages for assessing the risk of non-reporting biases and will be useful to researchers, thus being worth popularizing and applying.
The planning and reporting of synthesis questions in systematic review of intervention have a direct and important impact on the validity of the evaluation and the credibility of the results. Planning helps to reduce bias in the evaluation process and ensure the reproducibility of data synthesis. However, the field of systematic review currently lacks specific checklists and tools to guide how to plan and report these issues. The InSynQ (Intervention Synthesis Questions) checklist is a tool designed for planning and reporting data synthesis issues in systematic reviews of interventions. Its goal is to promote the standardization of systematic review methods, support systematic review participants in planning and comprehensively reporting data synthesis issues and structures, and provide a more accurate evidence base for clinical decision-making.
