Improving the quality of reporting of systematic reviews of dose-response meta-analyses: a cross-sectional survey.

ABSTRACT: BACKGROUND:Dose-response meta-analysis (DRMA) is a useful tool to investigate potential dose-response relationship between certain exposure or intervention and the outcome of interest. A large number of DRMAs have been published in the past several years. However, the standard of reporting for such studies is not known. METHODS:Medline, Embase, and Wiley Library were searched for systematic reviews with DRMAs (SR-DRMAs) published from January 2011 to July 2017. We used the combination of PRISMA and MOOSE statements, containing 33 items, to assess the reporting of included SR-DRMAs. The adherence of reporting was defined as the proportion of SR-DRMAs meeting the reporting requirement of an item. We explored the association between five pre-specified variables with the total score of reporting on both fully as well as each domain of the checklist. RESULTS:In total, 529 SR-DRMAs were eligible. Ten out of 33 items were under reported, and this mainly refers to the methods domain: only a small proportion of SR-DRMAs stated whether a review protocol existed (45, 8.5%); clarified the qualifications of searchers (1.7%); presented full electronic search strategy (25.9%); described any effort to include all available studies (22.9%), described methods for languages other than English (27.4%), and stated the process for selecting studies (20.2%). Multiple regression analysis suggested that studies with more authors (regression coefficient?=?0.78; 95% CI: 0.35, 1.20; P

Project description:BackgroundThe QUOROM and PRISMA statements were published in 1999 and 2009, respectively, to improve the consistency of reporting systematic reviews (SRs)/meta-analyses (MAs) of clinical trials. However, not all SRs/MAs adhere completely to these important standards. In particular, it is not clear how well SRs/MAs of acupuncture studies adhere to reporting standards and which reporting criteria are generally ignored in these analyses.ObjectivesTo evaluate reporting quality in SRs/MAs of acupuncture studies.MethodsWe performed a literature search for studies published prior to 2014 using the following public archives: PubMed, EMBASE, Web of Science, the Cochrane Database of Systematic Reviews (CDSR), the Chinese Biomedical Literature Database (CBM), the Traditional Chinese Medicine (TCM) database, the Chinese Journal Full-text Database (CJFD), the Chinese Scientific Journal Full-text Database (CSJD), and the Wanfang database. Data were extracted into pre-prepared Excel data-extraction forms. Reporting quality was assessed based on the PRISMA checklist (27 items).ResultsOf 476 appropriate SRs/MAs identified in our search, 203, 227, and 46 were published in Chinese journals, international journals, and the Cochrane Database, respectively. In 476 SRs/MAs, only 3 reported the information completely. By contrast, approximately 4.93% (1/203), 8.81% (2/227) and 0.00% (0/46) SRs/Mas reported less than 10 items in Chinese journals, international journals and CDSR, respectively. In general, the least frequently reported items (reported≤50%) in SRs/MAs were "protocol and registration", "risk of bias across studies", and "additional analyses" in both methods and results sections.ConclusionsSRs/MAs of acupuncture studies have not comprehensively reported information recommended in the PRISMA statement. Our study underscores that, in addition to focusing on careful study design and performance, attention should be paid to comprehensive reporting standards in SRs/MAs on acupuncture studies.

Project description:BackgroundAn increasing number of systematic reviews assessed the safety of surgical interventions over time. How well these systematic reviews were designed and conducted determines the reliability of evidence. In this study, we aimed to assess the methodological quality of systematic reviews on the safety of surgical interventions.MethodsWe searched PubMed for systematic reviews of surgical interventions with safety as the exclusive outcome from 1st-Jan, 2015 to 1st-Jan, 2020. The methodological quality of eligible systematic reviews was evaluated according to the AMSTAR 2.0 instrument. The primary outcomes were the number of methodological weaknesses and the global methodological quality. The proportion of each methodological weakness among eligible systematic reviews was compared by three pre-defined stratification variables. The absolute difference of the proportion (PD) was used as the effect estimator, with the two-tailed z-test for the significance.ResultsWe identified 127 systematic reviews from 18,636 records. None (n = 0, 0.00%) of them could be rated as "high" in terms of the global methodological quality; in contrast, they were either rated as "low" (n = 18, 14.17%) or as "critically low" (n = 109, 85.83%). The median number of methodological weaknesses of these systematic reviews was 8 (interquartile range, IQR: 6 to 9), in which 4 (IQR: 2 to 4) were critical weaknesses. Systematic reviews that used any reporting guideline (e.g., domain 13, PD = -0.22, 95% CI: - 0.39, - 0.06; p = 0.01) and developed a protocol in advance (e.g., domain 6, PD = -0.20, 95% CI: - 0.39, - 0.01; p = 0.04) were less likely to have methodological weakness in some domains but not for the rest (e.g., domain 8, PD = 0.04, 95% CI: - 0.14, 0.21; p = 0.68; with protocol vs. without).ConclusionsThe methodological quality of current systematic reviews of adverse events with surgical interventions was poor. Further efforts, for example, encouraging researchers to develop a protocol in advance, are needed to enhance the methodological quality of these systematic reviews.
