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.

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.
