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.

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.

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.

Using a similar process to other appraisal tools,37 we reviewed the relevant literature to develop a concise background on CA of CSSs and to ensure no other relevant tools existed. CA of the literature is a vital step in evidence synthesis and therefore evidence-based decision-making in a number of different disciplines. , bias arising from the randomization process, bias due to deviations from intended interventions, the ascertainment of either the exposure or outcome of interest for case-control or cohort studies respectively.

Bias (a systematic error, or deviation from the truth, in results or inferences5) and study design are other areas that need to be considered when assessing the quality of included studies as these can be inherent even in a well-reported study. 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.

Prevalence and Risk Factors of Chronic Kidney Disease among Type 2 Feedback from the different groups was assessed and any changes to the CA tool were made accordingly. A consensus of 80% was required from the Delphi panel for any component to be included in the final tool. However, it has been debated that quality numerical scales can be problematic as the outputs from assessment checklists are not linear and as such are difficult to sum up or weight making them unpredictable at assessing study quality.39 ,42 ,43 The AXIS tool has the benefit of providing the user the opportunity to assess each individual aspect of study design to give an overall assessment of the quality of the study.
