ObjectiveTo overview the systematic reviews on efficacy and safety of hyperbaric oxygen in treatment of diabetic foot.MethodsCNKI, CBM, VIP, WanFang Data, The Cochrane Library, PubMed and EMbase databases were searched to collect systematic reviews or meta-analyses on the efficacy and safety of hyperbaric oxygen therapy for diabetic foot from inception to November 17th, 2019. Two researchers independently screened literature and extracted data. Then, AMSTAR 2 tool and PRISMA statement were used to evaluate the methodological quality and reporting quality of included systematic reviews, and the outcome indicators were comprehensively analyzed.ResultsA total of 10 systematic reviews were included. The results of AMSTAR 2 suggested that 6 systematic reviews were of extremely low quality, 3 of low quality, and 1 of high quality. The PRISMA score ranged from 16.5 to 27. The results of the included systematic reviews showed that hyperbaric oxygen therapy might be superior to other interventions in ulcer healing rate and large amputation rate without increasing the risk of adverse events. ConclusionsThe existing systematic reviews/meta-analysis evidence shows that hyperbaric oxygen therapy may have certain curative effect on diabetic foot, however, its methodology and report quality evaluation are insufficient.
ObjectiveTo get known of the application of Preferred Items of Systematic Review and Meta Analysis (PRISMA). MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 10, 2013), CBM, WanFang Data and CNKI, to collect relevant literature about the application of PRISMA during 2009-2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and then bibliometric analysis was performed using Excel software. ResultsWe finally included 175 papers, including 26 conference abstracts and 149 full texts. The results of bibliometric analysis of full texts showed that, they were published in 118 journals, and PRISMA official website announced that 176 journals endorsed the application of PRISMA. According to study type, there were 111 systematic reviews and meta-analyses (SRs/MAs) for development and reporting, 20 overviews of SRs for reporting quality assessments, 7 versions of PRISMA interpretation, and 11 articles of other kinds. In 131 SRs/MAs as well as overviews, the studies about western medicine accounted for 77.8%, followed by public health (8.4%), and traditional Chinese medicine (4.6%). ConclusionThe application of PRISMA statement is still at the first phase and mainly confined to the field of western medicine, which needs more attention and understanding. Thus, it's necessary to interpret and disseminate the PRISMA statement.
Objective To assess the methodological quality and reporting quality of meta-analysis published in Chinese Acupuncture & Moxibustion. Methods We searched CNKI database to collect meta-analysis published in Chinese Acupuncture & Moxibustion up to 2015. Methodological quality assessment was carried out using AMSTAR tool, and quality assessment was carried out by PRISMA checklist. Data analysis was performed by using SPSS 19.0 software. Results A total of 31 meta-analyses were enrolled. Among all the 31 meta-analyses, the first authors came from 19 institutions, and 21 meta-analysis were supported by fundings. All meta-analyses were about the evaluations of acupuncture intervention, involving 10 disease systems (ICD-10) and sub-health. The mean score of the methodological assessment was 7.42±1.13. In addition, the mean score of reporting quality was 18.79±2.04. Conclusion The meta-analyses published in Chinese Acupuncture & Moxibustion have high quality on methodology as well as reporting. Due to the limited quality and quantity of included studies, the above results are needed to be further assessed by more studies.
ObjectiveTo investigate the reporting and methodological quality of systematic reviews/ meta-analyses conducted by hospital pharmacists in China, so as to improve the quality of systematic reviews/ meta-analyses in this field. MethodsThe literatures were retrieved from CNKI, WanFang Data, VIP, CBM, CMCI, PubMed, EMbase, The Cochrane Library from the establishment date to March 17th, 2016. According to the inclusive and exclusive criteria, authors independently screened and extracted the published information. Reporting and methodological quality of included reviews were evaluated by PRIMSA statements and AMSTAR checklists. Data analysis was conducted by using Excel 2013 software and SPSS 20.0 software. ResultsOne thousand and eighteen systematic reviews/ meta-analyses were included, including 871 Chinese literatures and 147 English literatures. The average score of PRIMSA was 18.41±2.84, and the average score of AMSTAR was 7.38±1.28. The main problems of PRIMSA were structured summary, objectives, protocol and registration, additional analyses and funding. The main problems of AMSTAR were priori design, status of publication and list of studies (included and excluded). Univariate analysis showed that some factors could improve the quality of methodology and reporting, including studies in English (P<0.000 1), published after checklists' (P<0.000 1), hospital in higher-level (P<0.000 1), illuminating the funding or interest conflict (P<0.000 1). Pearson analysis indicated that linear correlation were detected between PRISMA scores and AMSTAR scores (P<0.000 1), as well as citations and AMSTAR scores (P=0.045). ConclusionEvidenced-based pharmacy in hospital has developed rapidly, the quality of methodology and reporting have increaseed year by year, but further improvement should be considered in different aspects. The methods to evaluate the clinical application of these systematic reviews/ meta-analyses should be developed in the future.
ObjectivesTo assess the methodological and reporting quality of surgical meta-analyses published in English in 2014.MethodsAll meta-analyses investigating surgical procedures published in 2014 were selected from PubMed and EMbase. The characteristics of these meta-analyses were collected, and their reporting and methodological quality were assessed by the PRISMA and AMSTAR, respectively. Independent predictive factors associated with these two qualities were evaluated by univariate and multivariate analyses.ResultsA total of 197 meta-analyses covering 10 surgical subspecialties were included. The mean PRISMA and AMSTAR score (by items) were 22.2±2.4 and 7.8±1.2, respectively, and a positive linear correlation was found between them with a R2 of 0.754. Those meta-analyses conducted by the first authors who had previously published meta-analysis was significantly higher in reporting and methodological quality than those who had not (P<0.001). Meanwhile, there were also significant differences in these reporting (P<0.001) and methodological (P<0.001) quality between studies published in Q1 ranked journals and (Q2+Q3) ranked jounals. On multivariate analyses, region of origin (non-Asiavs. Asia), publishing experience of first authors (ever vs. never), rank of publishing journals (Q1 vs. Q2+Q3), and preregistration (presence vs. absence) were associated with better reporting and methodologic quality, independently.ConclusionThe reporting and methodological quality of current surgical meta-analyses remained suboptimal, and first authors' experience and ranking of publishing journals were independently associated with both qualities. Preregistration may be an effective measure to improve the quality of meta-analysis, which deserves more attention from future meta-analysis reviewers.
The PRISMA aims to enhance the transparency and reporting quality of systematic reviews. PRISMA 2020 is an update version of PRISMA 2009, which was published in BMJ in March, 2021. This article compared the PRISMA 2020 and PRISMA 2009, interpreted PRISMA 2020 with representative examples, aiming to help Chinese scholars better understand and apply this reporting guideline, thus to improve the reporting quality of systematic reviews.
ObjectiveTo carry out a retrospective study of the reporting quality and current situation of the systematic reviews (SRs)/meta-analyses (MAs) in pediatric field in China, as well as compliance with the PRISMA and MOOSE guidelines. MethodsSeven core Chinese pediatric journals were hand-searched. Two reviewers extracted data independently using predesigned data extraction form, crosschecked data, and discussed to solve discrepancy. The PRISMA and MOOSE guidelines were used to assess the reporting quality respectively, and subgroup analysis was conducted by different total cites and different published time. SPSS 22.0 was used to for statistical analysis. Percentage was used to describe categorical data and Chi-square test was used to compare the difference among groups. ResultsA total of 157 SRs/MA were included. The proportion of SRs/MA related to interventions was the biggest (61.1%, 96 SRs/MA). (1) The coincidence rate of SRs/MA related to interventions in the PRISMA checklist was better:the coincidence rate of twenty entries was above 50%; (2) The coincidence rate of observational SRs/MA in the MOOSE guidelines was not so good:the coincidence rate of 15 entries was less than 50%, even some of them were less than 20%. There were no significant difference between different total cites (≤5 vs. > 5) in PRISMA and MOOSE guidelines. (3) The coincidence rate of SRs/MA related to interventions had been improved to some extent in most of items after the PRISMA guidelines published, and the differences were statistically significant respectively in No. 8, 19, 20, and 23 (P≤0.05). ConclusionsThe number of SRs/MA published in the pediatric journals in China is increasing generally, the coincidence rate of SRs/MAs related to interventions have been obviously improved after the PRISMA guidelines published, and it's better than the coincidence rate of observational SRs/MAs in MOOSE guidelines. In a word, we should pay more attention to the quality of SRs/MAs, but not just the number.
Living systematic reviews (LSR) represent an evolving methodology for systematic review that is continuously updated to incorporate new evidence in a timely manner, ensuring that healthcare professionals and policymaker shave access to the most last information to make optimal decisions. The global publication of LSR has been a rapid increase. But the quality of reporting remains to be enhanced. In 2024, the PRISMA-LSR working group, in conjunction with the characteristics of LSR to form the reporting standards for living systematic reviews, which plays a significant role in promoting the transparent, complete, and accurate reporting of LSR. It has been published in the BMJ journal. This article interpreted PRISMA-LSR with representative examples, aiming to provide a reference for the standardization of LSR by domestic scholars.
The PRISMA-DTA Statement is an expanded checklist of the original PRISMA, which is aimed at improving the reporting quality of the systematic review or meta-analysis of diagnostic test accuracy studies. It was published on JAMA in January 2018. This paper explained it and provided reference for improving the reporting quality of systematic review/meta-analysis of DTA for Chinese authors.
The purpose of a scoping review is to help researchers gain a systematic and comprehensive understanding of the current state of development in a field. In this paper, we explained the background and core contents of the scoping review report specification checklist (PRISMA extension for scoping reviews, PRISMA-ScR) and interpreted each item with examples to guide domestic scholars to write scoping reviews and improve their reporting quality.
