Traditionally, evidence-based practice has been about using systematic reviews of randomised controlled trials (RCTs) to inform the use of interventions.10 However, other types/designs of research studies are becoming increasingly important in evidence-based practice, such as diagnostic testing, risk factors for disease and prevalence studies,10 hence systematic reviews in this area have become necessary. Critical appraisal is much more than a 'tick box' exercise. Cross-sectional studies (CSSs) are one of those study designs that are of increasing importance in evidence-based medicine (EBM). 0000118741 00000 n The tool was also reduced in size on each round of the Delphi process as commentators raised concerns around developing a tool with too many questions. The initial review of existing tools and texts identified 34 components that were deemed relevant for CA of CSSs and were included in the first draft of the tool (see online supplementary table S2). The AXIS tool is therefore unique and was developed in a way that it can be used across disciplines to aid the inclusion of CSSs in systematic reviews, guidel Development of a critical appraisal tool to assess the quality of cross-sectional studies (AXIS) BMJ Open.
