<h3>What is grade ?</h3>
A transparent framework for creating and presenting evidence summaries, GRADE (Grading of Recommendations, Assessment, Development and Evaluations) offers a systematic method for making recommendations for clinical treatment. [1-3] More than 100 organizations throughout the world have formally endorsed GRADE, making it the most extensively used technique for evaluating the quality of evidence and for formulating recommendations.

It is reasonable for two people analyzing the same collection of evidence to reach divergent judgments regarding its veracity. What GRADE does offer is a transparent and reproducible methodology for rating the degree of certainty in the evidence.
