Objective: To evaluate the methodological qualities of the systematic review/Meta-analysis (SR/MA) of Xingnaojing in treating stroke. Method: Chinese biomedical literatures and journals were searched through China National Knowledge Infrastructure
VIP
Wanfang and Cochrane databases. The systematic review/Meta-Analysis of Xingnaojing in treating stroke was included. The search time was ended in January 2015.The Oxman-Guyatt Overview Assessment Questionnaire (OQAQ) Scale was used to evaluate the methodological and reporting quality of the included SR/MA literatures. Result: A total of 13 SR/MA literatures were included. The included SR/MA had the following shortcomings:incomplete literature search
high selection bias
poor methodological quality of the original articles and low accuracy. The original articles in SR/MA had the following shortcomings:unclear randomizatioon methods
unclear concealment
no blinding
loss to follow-up or intent-to-treat (ITT)
uncertain co-intervention or contamination. Conclusion: The methodological qualities of domestic SR/MA of Xingnaojing in treating stroke were poor. It was necessary to improve the methodological qualities of SR/MA and standardize the experiment design
especially to improve the literature search and reduce the selection bias. The criteria recommended by Cochrane shall be adopted for the quality evaluation of the included original literatures.
