Example appraisal sheets are provided together with several helpful examples. High quality and complete reporting of studies is a prerequisite for judging quality.17 ,18 ,35 For this reason, the AXIS tool incorporates some quality of reporting as well as quality of design and risk of biases to overcome these problems.
