Critical appraisal checklists help to appraise the quality of the study design and (for quantitative studies) the risk of bias. Critical appraisal tools for cross-sectional studies are the AXIS, [ 4 ] JBI, [ 5 ] Nested Knowledge [ 6 ] tools; for randomised controlled trials are Nested Knowledge, [ 6 ] Cochrane Risk of Bias Tool, [ 7 ] [ 8 ] JBI ...
