Participants were asked to add any additional comments they had regarding each component. The Appraisal tool for Cross-Sectional Studies (AXIS) was developed - 20 point questionnaire that addressed study quality and reporting. There was a great variability among items assessed in each tool. Therefore, a robust CA tool to address the quality of study design and reporting to enable the risk of bias to be identified is needed.

Summary:JBI Critical appraisal tools have been developed by the JBI and collaborators and approved by the JBI Scientific Committee following extensive peer review.

Participants were qualified a mean of 17.6years (SD: 7.9) and the panel was made up of participants from varying disciplines (table 1). In time, as seen from Figure 4, the cross-sectional geometry becomes increasingly deformed, with some interesting topological substructure evident by t = 1.4. A CA tool to assess the quality and risk of bias in CSSs (AXIS), along with supporting help text, was successfully developed by an expert panel using Delphi methodology. Development of a critical appraisal tool to assess the quality of cross to even a few decades. It was the view of the Delphi group that the assessment as to whether the published findings of a study are credible and reliable should relate to the aims, methods and analysis of what is reported and not on the interpretation (eg, discussion and conclusion) of the study. If not, could this have introduced bias? If consensus was 50%, components were removed from the tool.

The study compared five different algorithms to find the best model, adding to the limited research on stroke risk prediction in China. It is important to note that a well-reported study may be of poor quality and conversely a poorly reported study could be a well-conducted study.33 ,34 It is also apparent that if a study is poorly reported, it can be difficult to assess the quality of the study.

To ensure that the tool was developed to a high standard, a high level of consensus was required in order for the questions to be retained.31 ,32 ,39 There was a high level of consensus between veterinary and medical groups in this study, which adds to the rigour of the tool but also demonstrates how both healthcare areas can cooperate effectively to produce excellent outcomes. If participants failed to respond to a specific round, they were still included in the following rounds of the Delphi process. Critical appraisal tools for cross-sectional studies are the AXIS tool[4] and JBI tools;[5] for randomised controlled trials are Cochrane Risk of Bias Tool,[6][7] JBI tool[8] and CASP tools.
