Abstract：Existing risk of bias assessment tools are primarily designed for traditional pairwise Meta-analysis and fail to comprehensively evaluate the unique sources of bias risk inherent in network Meta-analysis.Therefore,Lunny and others developed a tool the Risk of Bias in Network Meta-analysis(RoB NMA),designed specifically to evaluate potential biases in network Meta-analysis arising from aspects such as intervention selection and network structure,effect modifiers,and statistical analysis.This article aims to interpret the development background,item content,and evaluation process of the RoB NMA tool,providing reference and guidance for domestic researchers of its application.
