For round 2 (undertaken in May 2013), 11 components remained the same and did not require testing for consensus as this was established in round 1; 9 components that had previously reached consensus were incorporated with the 13 components that required modification to create 10 new components (see online supplementary table S4). 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.

We identified an appraisal tool, developed in Spanish, which specifically examined CSSs.15 Berra et al essentially converted each reporting item identified in the STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) reporting guidelines and turned them into questions for their appraisal tool. Two contacts felt they were not suitably qualified for the Delphi panel (n=2); one was retired and the other was a lecturer with research and clinical duties. 13.5.2.3 Tools for assessing methodological quality or risk of bias in non-randomized studies. Detailed explanatory document provided with the tool Expanded explanation of each question The AXIS tool is intended to be an organic item that can change and improve where required, based on user 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. During round 1 (undertaken in February 2013) of the Delphi process, 20 components reached consensus, 13 components were assessed to require modification and it was deemed appropriate to remove 4 components from the tool. The number of participants from each discipline enrolled in the Delphi panel for the development of the AXIS tool. A numerical scale to reflect quality was not included in the final tool, which may be perceived as a limitation. This type of study design can be used to assess associations (e.g., exposure to specific risk factors may correlate with particular outcomes). How precise is the estimate of the effect? Seven (1, 4, 10, 11, 12, 16 and 18) of the final questions related to quality of reporting, seven (2, 3, 5, 8, 17, 19 and 20) of the questions related to study design quality and six related to the possible introduction of biases in the study (6, 7, 9, 13, 14 and 15). The ROBINS-I is a tool developed to assess risk of bias in the results of non-randomized studies that compare health effects of two or more interventions. Children (Basel). However, the purpose of a Delphi study is to purposely hand pick participants that have prior expertise in the area of interest.40 The Delphi members came from a multidisciplinary network of professionals from medicine, nursing and veterinary medicine with experience in epidemiology and EBM/EVM and exposure to teaching and areas of EBM that were not just focused on systematic reviews of RCTs. By providing this subjectivity, AXIS gives the user more flexibility in incorporating quality of reporting and risk of bias when making judgements on the quality of a paper. 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. of General Practice, University of Glasgow, UK, http://cobe.paginas.ufsc.br/files/2014/10/MINORS.pdf.

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. How to choose an appropriate quality assessment tool The survey examines a nationally representative sample of about 5,000 persons located across the country each year. 0000120034 00000 n 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. Of those that took part, 8 were involved in clinical, teaching and research duties and 10 were involved in research and teaching, 5 of the participants were veterinary surgeons and 6 were medical clinicians. This cross-sectional study was conducted in Ghaem Hospital of Mashhad. 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. It is applicable where the aim of the qualitative component is to draw out the informants understandings and perceptions. 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 objectives of this cross-sectional study were: 1) to estimate the prevalence and characterize the severity of periodontal disease in a population of dogs housed in commercial breeding facilities; 2) to characterize PD preventive care utilized by facility owners; and 3) to assess inter-rater reliability of a visual scoring assessment tool.
