As the need for the inclusion of CSSs in evidence synthesis grows, the importance of understanding the quality of reporting and assessment of bias of CSSs becomes increasingly important. This is usually in the form of a single survey, questionnaire, or observation. A longitudinal study is a type of correlational research study that involves looking at variables over an extended period of time. The aim of this study was to develop a critical appraisal (CA) tool that addressed study design and reporting quality as well as the risk of bias in cross-sectional studies (CSSs). Risk of Bias Tool. A cross-sectional correlation arises when sample studies focus on (an) event (s) that happened for multiple firms at the same day (s). Cross sectional studies are carried out at one point in time, or over a short period of time. Critical appraisal (or quality assessment) in evidence based medicine, is the use of explicit, transparent methods to assess the data in published research, applying the rules of evidence to factors such as internal validity, adherence to reporting standards, conclusions, generalizability and risk-of-bias.

The AXIS tool focuses mainly on the presented methods and results. The use of a multidisciplinary panel with experience in epidemiology and EBM limits the effect of using a non-representative sample, and the use of the Delphi tool is well recognised for developing consensus in healthcare science.38 The selection of a Delphi group is very important as it effects the results of the process.31 As CSSs are used extensively in human and veterinary research, it was appropriate to use expertise from both of these fields. If consensus was lower than 80% but >50%, the component was considered for modification or was integrated into other components that were deemed to require reassessment for the next round of the Delphi.
