Objective To evaluate the reporting quality of systematic reviews (SRs)/meta-analyses on acupuncture focusing on literature screening results and explore the influencing factors of the complete reporting.Methods PubMed, EMbase, CNKI, WanFang Data, and VIP databases were searched to collect SRs/meta-analyses on acupuncture from inception to December 31st, 2019. Two reviewers independently screened literature, extracted data and evaluated the reporting quality of literature screening results of SRs/meta-analyses on acupuncture based on PRISMA statement. Logistic regression model analysis was applied to explore the influencing factors of the complete reporting rate of literature screening results. Statistical analysis was performed by using Excel 2016 and SPSS 16.0 software.Results A total of 1 227 SRs/meta-analyses were included. Only 62.3% SRs fully reported the four parts of literature screening results. The parts with a low reporting rate included the number of studies assessed for eligibility (73.2%) and the reasons for exclusions at each stage (67.0%). And the reporting rate of the literature screening flowchart was also low (63.6%). The reporting rate of literature screening results in Chinese SRs was lower than that in English SRs, and there was significantly statistical difference (P<0.001). Multivariate logistic regression analysis showed that the type of published journal, publication year, pages of article and the number of searched databases were correlated with the complete reporting rate of literature screening results (P<0.001).Conclusions The complete reporting rate of the literature screening results of SRs on acupuncture is low, especially in Chinese SRs. The complete reporting rate of literature screening results is significantly higher for SRs published after PRISMA statement, in SCI journals, with longer length and more searched databases.
