Evaluation of the Methodological and Reporting Quality of Systematic Reviews/Meta-analysis on Traditional Chinese Medicine for Chronic Heart Failure
To evaluate the methodology and reporting quality of systematic reviews and meta-analysis of traditional Chinese medicine (TCM) for chronic heart failure (CHF).
Methods
2
The literatures were searched in China National Network Knowledge Infrastructure (CNKI),Chinese Scientific Journal Database (VIP),Chinese BioMedical Literature Database (CBM) and Wanfang Database, Pubmed, Scopus, and Cochrane library from their inception time to December 31st, 2022. Systematic reviews and meta-analyses on TCM for CHF, either in English or Chinese, were included. The methodological and reporting quality of the included systematic reviews/ meta-analyses were assessed using AMSTAR scale and PRISMA tool, respectively.
Results
2
A total of 192 systematic reviews/meta-analyses were included, involving 178 Chinese and 14 English papers, and the overall number of publications showed an upward trend from 2008 to 2022. The average score of AMSTAR scale was 6.46±1.32, and the Chinese and English papers scored 6.31±1.24 and 8.29±0.83, respectively. Only 3 literatures (1.6%) registered the pre-study protocol before initiation. None provided a list of included and excluded studies, and only 33 (17.2%) considered the publication status in the inclusion criteria. Only 83 studies (43.2%) noted conflicts of interest. Four Chinese literature and six English literature were of high quality; 161 Chinese and 8 English literatures were evaluated as moderate quality; 13 low-quality literatures were all in Chinese. The average PRISMA score was 19.95±3.13, and that of the Chinese and English papers was 19.81±3.11 and 21.75±2.92, respectively. Five papers (2.6%) reported protocol and registration information, and 69 papers (35.9%) reported other analytical results.
Conclusion
2
Regarding the methodological and reporting quality of the systematic reviews/ meta-analyses on TCM for CHF, there are still certain problems, such as lack of preliminary study design, failure to report relevant conflict of interest, lacking a list of included and excluded studies, and insufficient reporting of results, and the overall quality of Chinese literature was lower than that of English literature, indicating that the methodological and reporting quality need to be further improved.
