Evidence certainty grading of network meta-analysis:method update and case application
Network meta-analysis(NMA)is a method that can compare and rank the effects of different interventions,which plays an important role in evidence translation and evidence-based decision-making.In 2014,the GRADE working group first introduced the GRADE method for NMA evidence certainty grading.Since then,its method system has been gradually supplemented and improved.In recent years,the GRADE working group has further improved the methods for evaluating intransitivity and imprecision in NMA,and has made recommendations for the presentation and interpretation of NMA results,forming a complete methodological chain of NMA evidence certainty grading and result interpretation consisting of 6 steps.Our team updated the method system of GRADE applied in NMA with specific cases to provide references for relevant researchers.
