RESUMO
Objective: To assess the quality for meta-analysis on prevention and treatment of coronary artery disease (CAD) in China. Methods: We systemically searched 4 Chinese databases of VIP, CNKI, CBM and Wan Fang for their meta-analysis on CAD prevention and treatment from 1987-01 to 2013-10. According to inclusion and exclusion criteria, 2 researchers independently screened and cross-checked all the literatures. The qualities of methodology and report were evaluated by R-AMSTAR and PRISMA scales. Results: A total of 201 literatures were enrolled for our study. The average score of methodology quality was (24.65±3.97), no literature met all required items, and the major problems were as lack of“a priori design”, insufifcient and bias of data selection combining inappropriate data synthesis. The average score of report quality was (17.20 ± 2.90), no literature met all 27 required items, and the major problems were as incomplete report of abstract, objective, protocol and registration, incomplete data collection/analysis, using and publishing bias information, incomplete quality assessment. Conclusion: Both of methodology and report of meta-analysis for CAD prevention and treatment have quality problems at different levels, further improvement should be expected.
