A New Literature Evaluation System—GRADE System

Evidence-based medicine is an approach to medical practice intended to optimize decision-making by evaluating currently available evidence. Proper evaluation of clinical literature could not only facilitate development of clinical guidelines, but also help make good decision of medical practice. Although current literature-evaluating systems improve the progress of literature evaluation, but it is still unsolvable to correctly resolve the uncertainty between different opinions. This article is to introduce a new literature-evaluating system by elaborating how it grades literature and how it resolves the dispute between different opinions, which might help clinical practitioners and policy makers make better decisions.
