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. Were the limitations of the study discussed?
