A comprehensive explanatory text is often used in appraisal tools for different types of study designs as it aids the reviewer when interpreting and analysing the outputs from the appraisal.12 ,1720 This approach was also used in the development of the AXIS tool where a reviewer can link each question to explanatory text to aid in answering and interpreting the questions. It involves identifying a defined population at a particular point in time At the same time measuring outcome of interest e. g. obesity. 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. 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.
