Example 8a makes clear the size of the effect even for readers who have difficulty interpreting relative risks and confidence intervals. Analytic framework 3. Explanation: Irrespective of the strength and nature of the results reported in the abstract, readers should be able to assess the questions that the review intended to address. The potential for health benefits may depend on baseline housing conditions and careful targeting of the intervention. Yes Explanation: Studies of the relationship between pharmaceutical company funding and results of clinical trials have shown that sponsored studies are more likely to have outcomes favouring the sponsor [29],[30]. Examples: 8a. PLoS Med 10(4): Of those clicks, abstracts will be represented about 2.5 times more often than full texts of articles [2]. Methods: This systematic literature review was guided by the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). For randomised trials, common components include: appropriate generation of the allocation sequence [24], concealment of the allocation sequence [20], blinding of participant and health care providers, blinding of outcome assessors [22], assessment of incomplete outcome data [25], and selective outcome reporting [26]. For example, the strengths and limitations may be stated at the end of the Results, under a separate heading, or with the Discussion or Conclusions, depending on journal requirements. We also wanted to provide a checklist enabling the items suggested to fit into any set of headings mandated by a journal or conference submission. Add your ORCID here. Abstracts of systematic reviews are very important, as some readers cannot access the full paper, such that abstracts may be the only option for gleaning research results. “Four potentially eligible trials were not included in the meta-analysis because mortality data by age group were not available.”, 9b. Conversely, a large proportion of systematic reviews are published by health technology agencies in non-English speaking countries [1], many of which provide only the abstract in English. The abstract of a systematic review should provide a structured summary that enables a quick assessment of the review's validity and applicability, and easy identification in electronic searching. PMID: 20609983. We encourage journals and conference organisers to endorse the use of PRISMA for Abstracts, in a similar way to CONSORT for Abstracts [33]. National Center for Biotechnology Information, National Library of Medicine, Washington DC, United States of America, Affiliation The work is made available under the Creative Commons CC0 public domain dedication. Systematic reviews are not a solo effort; a team of several people is required for this type of review. The objectives in an abstract should convey succinctly the broad aims of the systematic review. Fewer than 200 cases of primary adrenal lymphoma (PAL) have been reported. READ THE ORIGINAL ABSTRACT HERE. Indeed, for readers who do not understand the language of publication of the article, the translated abstract may have far more relevance than the full-text article. Even people going straight to a PDF or full text are likely to start, and perhaps end, with reading the abstract. This approach can be seriously misleading, however, and should be discouraged. Multisystem inflammatory syndrome is a new pediatric disease associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is dangerous and potentially lethal. Similarly, the abstract should only draw conclusions that are substantiated by data from the full report and analyzed as described in the protocol, rather than selectively emphasising interesting results that were a minor or ad hoc component of the analysis. It is therefore a means of alerting researchers to systematic reviews that are in progress, and serves as a public record of the proposed systematic review. Despite published guidance on writing the abstract in the PRISMA Statement guiding the reporting of systematic reviews in general and elsewhere, evaluations show that reporting of systematic reviews in journal and conference abstracts is poor. They provide readers with a series of headings, generally about the purpose, methods, results, and conclusions of the report, and have been adopted by many journals and conferences. Direction of the effect (i.e., which group is favoured) and size of the effect in terms meaningful to patients and clinicians. The wording should indicate the direction of the effect (e.g., lower, fewer, reduced; greater, more, increased) and the size of the effect using familiar units such as percentages, days, or kilograms. A particularly difficult area is the Discussion section of an abstract. Thus, the main function of an abstract of a systematic review should be to signal its systematic methodology. We also suggest that peer and editorial review processes related to the abstract should explicitly check this. Your email address will not be published. A checklist is not sufficient to ensure good abstract writing. The guidance for abstracts includes twelve specific recommendations which outline what key pieces of information should be included in the abstract, with the intention of avoiding accidental omission or misinterpretation, and to help readers decide whether … “Length of hospital and critical care unit stay were both modestly reduced in the tested group compared with the control group, with a mean difference of −1.22 day (CI, −2.31 to −0.14 day) and −0.56 day (CI, −1.06 to −0.05 day), respectively.”, 8c. We do not advocate that abstracts replace full articles in informing decision making, but we recognise that for many time-pressed readers, or for those with limited access to the full texts of reports, it is important that abstracts contain as much information as is feasible within the word limit of abstracts. Abstract and Conclusion of Systematic Review was first posted on December 6, 2020 at 5:01 am. We developed this document using the template for the PRISMA Statement [11], which in turn was based on the methods of the CONSORT Group [14],[15]. When readers screen the title of an article, and parts of its abstract, they try to determine whether or not to devote their scarce time to reading on. Where possible, given space limitations, the number of studies and participants for each main outcome should be stated, particularly if only a small proportion of the total number of studies or patients in the systematic review contributed information on a particular outcome. A systematic review of the literature on medical cannabinoids in children and adolescents was performed according to the Preferred Reporting Items for Systematic Reviews and Meta- Analyses (PRISMA) statement. PRISMA for Abstracts: Reporting Systematic Reviews in Journal and Conference Abstracts. The question will serve as a reference point throughout the research an… The systematic review is a scientific tool that can help with this difficult task. Examples: 4a. Examples: 2a. Primary source of funding for the review. It is therefore an important part of a systematic review to assess the validity of individual studies, and the risk that they will overestimate the true intervention effect. Abbreviations: Funding: This research was supported (in part) by the Intramural Research Program of the NIH, National Center for Biotechnology Information (National Library of Medicine). We recognise that journals have developed their own set of headings that are considered appropriate for reporting systematic reviews, and it is not our intention to suggest changes to these headings, but to recommend what should be reported under them. The PRISMA for Abstracts checklist focuses on truthful representation of a systematic review in an abstract. “A small difference was found between acupuncture and placebo acupuncture: standardised mean difference −0.17 (95% confidence interval −0.26 to −0.08)… [in favour of acupuncture]…, corresponding to 4 mm (2 mm to 6 mm) on a 100 mm visual analogue scale.”. The meeting began with a review of the literature about abstract structure and content, followed by a review of the checklist items as proposed by the survey respondents. As keywords or key terms are used in a search, their usefulness will be determined by the search results. Only those who completed round one were invited to participate in rounds two and three. The committee generated a list of items from PRISMA and other sources of guidance and information on structured abstracts and abstract composition and reporting [7],[11],[12], which were found using a thorough search of the literature. One hundred and forty-seven participants, who were authors of research on abstracts, established authors of systematic reviews, methodologists or statisticians related to systematic reviews, and journal editors, were invited by email to complete the three rounds of the web-based survey. Systematic review allows the assessment of primary study quality, identifying the weaknesses in current experimental efforts and guiding the methodology of ... and conclusion/inference should be provided in the review abstract. Assemble the systematic review team 3. The abstract should include the main source of funding for the systematic review, whether from host institutions or from external bodies. “PROSPERO registration: CRD42011001243.”. It is designed to be used in conjunction with the previous guidance for the reporting of an entire systematic review – the PRISMA statement. A key step in the process of systematic review is citation screening, which involves manual review of study report titles and abstracts to identify potentially eligible articles for inclusion in the review . Study and report characteristics used as criteria for inclusion. Trials in which passengers wore a stocking on one leg but not the other, or those comparing stockings and another intervention were also eligible.”, Examples – report characteristics: 3c. The present review was not registered. Although much of the guidance may seem simple and straight forward, it’s important to note that readers clearly find such tools useful: at the time of writing, the PRISMA guidance had received over 90,000 views and over 750 citations. If the conclusions of the review differ substantially from previous systematic reviews, then some explanation might also be provided. Despite the adoption of structured abstracts, studies of the quality of abstracts of clinical trials have demonstrated that improvement is needed [8],[9], and a study of systematic review abstracts demonstrated that the direction of the effect or association could not be determined in one in four abstracts from the general and specialty medical literature [10].
