Cochrane library

Medline complete and Embase databases were searched through computer to collect relevant studies. Two authors independently collected information

and evaluated the methodological quality and grades of evidence of the included studies by AMSTAR scale and GARDE system. Result: A total of 12 studies involving 37 outcomes were included. The results of AMSTAR scale showed that the most problematic entry was that ‘was an early-stage design scheme provided’ (12 studies)

followed by the entry that ‘were the included selections and data extractions reproducible’ (8 studies)

and the entry that ‘was relevant conflict of interest indicated (8 studies). The results of the GRADE system showed that 5 outcomes were graded as ‘medium quality’

while the others were ‘low quality’ or ‘very low quality’ owing to research limitations (37 outcomes) and publication bias (32 outcomes). Conclusion: Currently

the methodological quality of reviews-Meta-analysis remains poor

with a low grade of evidence

so future studies should strictly designed according to the requirements of evidence-based medicine

so as to provide higher-quality evidences.
