Grade outcomes or studies: how to use grade approach correctly.

摘要

We would like to thank the authors of the letter to the editor by Mao et al. for their critical look at our article [1]. We would like to address their points. The GRADE approach was used to add to our identification of the quality of evidence of studies [2]. By using the GRADE in combination with the QAT the authors drew conclusions regarding quality of evidence [3]. We acknowledge the rules and guidelines of the GRADE approach but the authors wanted to use two quality tools in making a good identification of quality of evidence.
