If participants failed to respond to a specific round, they were still included in the following rounds of the Delphi process. We considered it reasonable to initially restrict the recommendations to the three main analytical designs that are used in observational research: cohort, case-control, and cross-sectional studies.

In each round, if a component had 80% consensus, it remained in the 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.

Evidence-based medicine (EBM) is a widely accepted scientific advancement in clinical settings that helps achieve better, safer, and more cost-effective healthcare. 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. 10.1136/bmj.323.7317.833 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. 0000108039 00000 n A national example of a cross-sectional study is the annual National Health and Nutrition Examination Survey (NHANES) which is a program of studies, begun in the early 1960's, designed to assess the health and nutritional status of adults and children in the United States.
