These reviews include qualitative, quantitative and mixed methods studies. Summary: Assessment of Multiple Systematic Reviews (AMSTAR) is a 37-item assessment tool used to assess the methodological quality of systematic reviews. The initial review of existing tools and texts identified 34 components that were deemed relevant for CA of CSSs and were included in the first draft of the tool (see online supplementary table S2). Relative Risk (RR) = risk of the outcome in the treatment group / risk of the outcome in the con-trol group. , Are the measurements/ tools validated by other studies? 2.

A number of publications were identified in the review and a number of key epidemiological texts were also identified to assist in the development of the new tool.1 ,11 ,12 ,15 ,17 ,2029 MJD and MLB used these resources to subjectively identify areas that were to be included in the CA tool. How precise is the estimate of the effect? 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. 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. Many of the questions are present in the CASP CAT. The panel was restricted to those that were literate in the English language and may therefore not be representative of all nationalities. Covidence includes the Cochrane Risk of Bias 2.0 quality assessment template, but you can also create your own custom quality assessment template. The first draft of the CA tool was piloted with colleagues within the Centre for Evidence-based Veterinary Medicine (CEVM) and the population health and welfare research group at the School of Veterinary Medicine and Science (SVMS), The University of Nottingham and the Centre for Veterinary Epidemiology and Risk Analyses in University College Dublin (UCD).

The CA tool was also sent via email to nine individuals experienced with systematic reviews in veterinary medicine and/or study design for informal feedback. 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. Present key elements of study design early in the paper. We have also included some information about developing your own CATs. This view is also seen in other appraisal tools, is shared by other researchers and can be seen by the absence of questions relating to the discussion sections in CA tools for other types of studies.12 ,16 ,20 ,28 ,36. In addition, the aim was to produce a help document to guide the non-expert user through the tool.

Methods Broad areas were identified Using a scoping review and key epidemiological texts. Prior to conducting the Delphi process, it was agreed that consensus for inclusion of each component in the tool would be set at 80%.31 ,32 This meant that the Delphi process would continue until at least 80% of the panel agreed a component should be included in the final tool. The interests and experiences of the panel will clearly have had an effect on the results of this study as this is common to all Delphi studies.31 ,41 The majority of Delphi studies are conducted using between 15 and 20 participants,31 so a panel of 18 is consistent with other published Delphi panels.
