Objective: To evaluate the methodological quality of the systematic review/Meta-Analysis (SR/MA) of Buyang Huanwu Tang in treatment of stroke by comparing with other interventions. Method: CMCC

Wanfang China National Knowledge Infrastructure

VIP and Cocranhe databases were searched to select the literature on systematic review/Meta-analysis (SR/MA) of Buyang Huanwu Tang and other interventions in treatment of stroke. The retrieval time limit was up to May 2015.Oxman-Guyatt Overview Assessment Questionnaire (OQAQ) Scale was used to evaluate the methodological and reporting quality of the eligible SR/MA. Result: A total of 92 SR/MA literature were obtained

and 9 of them were finally included. The included Meta analysis literature had the following shortcomings: no comprehensive literature search

high selection bias

poor methodological quality of the original articles

and poor accuracy of data consolidation method and premise. The experimental design of the original articles had the following shortcomings: unclear randomizatioon methods

no grouping concealment

no blinding

no reporting of intent-to-treat (ITT) analysis

uncertain co-intervention and contamination. Conclusion: The number of domestic and overseas literature on SR/MA of Buyang Huanwu Tang in treating stroke is gradually increasing in recent years

but few of them could reach high quality SR/MA

so it is necessary to improve the methodological quality and regulate the experimental design
