A cross-sectional study assesses risk factors and the outcome at the same moment in time. 10.1136/bmj.323.7317.833 The Cochrane collaboration has developed a risk of bias tool for non-randomised studies (ROBINS-I);14 however, this is a generic tool for casecontrol and cohort studies that do not facilitate a detailed and specific enough appraisal to be able to fully critique a CSS, In addition, it is only intended for use to assess risk of bias when making judgements about an intervention. A comprehensive numerical investigation into the cross-sectional behaviour and ultimate capacity of non . Results: In addition, well-developed appraisal tools have been created for readers assessing the quality of cohort and casecontrol studies;12 ,13 however, there is currently a lack of an appraisal tool specifically aimed at CSSs. A hyperlink to the online questionnaire with the tool was distributed to the panel using email.

If you decide to customize the quality assessment template, you cannot switch back to using the Cochrane Risk of Bias template. Delphi methods and use of expert groups are increasingly being implemented to develop tools for reporting guidelines and appraisal tools.18 ,19.

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, guidelines and clinical decision-making. The basis of a cross sectional study design is that a sample, or census, of subjects is obtained from the target population and the presence or the absence of the outcome is ascertained at a certain point.11 Various reporting guidelines are available for the creation of scientific manuscripts involving observational studies which provide guidance for authors reporting their findings.

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. We considered it reasonable to initially restrict the recommendations to the three main analytical designs that are used in observational research: cohort, case-control, and cross-sectional studies. Present key elements of study design early in the paper. Chapter 8 (Section 8.5) describes the 'Risk of bias' tool that review authors are expected to use for assessing risk of bias in randomized trials. Are the valid results of this study important? Relative Risk (RR) = risk of the outcome in the treatment group / risk of the outcome in the con-trol group. A newer tool, Appraisal Tool for Cross-Sectional Studies (AXIS) [ 8 ], was developed to address the absence of formal MQ tools for cross-sectional studies.
