This could be a cause for concern because it has been argued that any health research should begin with a SR of the literature [17]. Systematic reviews follow a clear structure, generally of the format, The abstract should be clearly structured, The introduction should summarise the topic and explain why the review is necessary. NOTE: If you are considering purchasing a book, buy the 2nd edition (2017). The next paragraph describes limitations of studies included and of the review process. This could refer to either insufficient formal training or insufficient mentoring. On other aspects of introduction there is no agreement on number of paragraphs, word limits and citations. Syst Rev 6, 253 (2017). PubMed  Recommendations for future studies are often made. The distinction between a systematic literature review and a literature review can often be confusing. Information covered in this guide Before you start, make sure you are ready. Survey responses were entered into a spreadsheet, checked by both authors and analysed using Microsoft Excel (Microsoft Inc., Redmond, WA, USA). It is wise to use more than one online database as each one includes a different range of journals. Google Scholar. 2013;2(1):9–14. The graduate program and the mentor need to ensure that a PhD candidate receives sufficient knowledge to complete the proposed thesis topic. Finally, participants were invited to leave their email address if they wanted to receive survey results. Livia Puljak. A systematic review is a complex piece of research that aims to identify, select and synthesise all research published on a particular question or topic. Systematic reviews (SRs) have been proposed as a type of research methodology that should be acceptable for a graduate research thesis.

They argued that, in an ideal situation, ‘the research community would accept systematic reviews as a research category of its own, which is defined by methodological criteria, as is the case for other types of research’ [8]. Systematic Reviews strongly encourages that all datasets on which the conclusions of the paper rely should be available to readers. This research was funded by the Croatian Science Foundation, grant no. Tags: featured, systematic essay writing, systematic literature review.

Such tables typically include the population studied, interventions and outcomes. Quantifying heterogeneity in a meta-analysis. Thus, it has been recommended that SRs should be included ‘whenever appropriate, as a mandatory part of any PhD program or candidature’ [18]. Therefore the first step is to prepare a protocol describing the aims and objectives of the experiment and the methods. de Vries RB, Wever KE, Avey MT, Stephens ML, Sena ES, Leenaars M. The usefulness of systematic reviews of animal experiments for the design of preclinical and clinical studies. Article  In 2016, we surveyed individuals in charge of European PhD programs from 105 institutions. Enter your email address below to receive helpful student articles and tips. Online survey used in the study. Systematic review allows the assessment of primary study quality, identifying the weaknesses in current experimental efforts and guiding the methodology of future research. PubMed  A PhD candidate can prepare a Cochrane SR as a part of the PhD thesis, yielding a high-impact publication [4]. Dtsch. The study is also not generalisable to Europe, as there are no universal criteria or expectations for PhD theses in Europe. Article  This finding could be a result of a lack of capacity and knowledge for conducting SRs in the particular institutions where the survey was conducted, and not general opinion related to learning a research method when conducting a PhD study. Inclusion and exclusion criteria should also be determined at this stage. Even in the same country, there may be different models and expectations for a PhD in different higher education institutions. Google Scholar. statement and It has recently been suggested that the overwhelming majority of investment in research represents an ‘avoidable waste’ [19]. This links to an example of such a form: Quality appraisal is perhaps the most central step, and there are a number of checklists which have been developed to help with this process. In most of the programs (37%; n = 22), the number of required manuscripts was three or more. The majority of respondents were neutral regarding the idea that scoping reviews or SRs should replace traditional narrative reviews preceding the results of clinical and basic studies in doctoral theses. Wright, R W, Brand, R A, Dunn, W and Spindler, K P (2007) ‘How to Write a Systematic Review’, Clinical Orthopaedics and Related Research’, 455:23-29. Biondi-Zoccai et al. Evidence synthesis Designing the Question The design of a research question requires careful selection of language, which mirrors the intent of the research. Refers to any combination of methods where one significant component is a literature review (usually systematic). PubMed Central  We had five such cases, so it is possible that institutions within the same university have different rules related to accepted research methodology in graduate PhD programs. What is the P roblem, condition or disease you are interested in?. The survey sent to the study participants can be found in an additional file (Additional file 1). Ann Intern Med. Two manuscripts were required in 30% (n = 18) and one was required in 33% (n = 20) of the programs. Most of the programs that accepted SRs as a research methodology acceptable for PhD theses had defined rules related to the use of an SR as part of a PhD thesis (Fig. This is valid not only for clinical trials, but also for other types of animal and human experiments [20]. Mahtani KR. Research Proposal (systematic review) Research Proposal (systematic review) Presentation Here is some information about how to present the assessment item. Glasgow: McGraw Open Press University; 2011. Just click on the links, left. 2). To the best of our knowledge, there are no reports on the acceptance of SRs as the basis for PhD theses. The majority of participants were not familiar with basic concepts related to SRs; questions about meta-analyses and the type of plots frequently used in SRs were correctly answered by only one third of the participants. The rough guide to systematic reviews and meta-analyses. A recent study indicated a number of opposing views and disadvantages related to SRs as research methodology for graduate theses, including lack of knowledge and understanding by potential supervisors, which may prevent them from being mentors and assisting students to complete such a study [5]. Some of the questionnaires (n = 15) were only partly completed. Med Teach. The review systematically searches, identifies, selects, appraises, and synthesizes research evidence relevant to the question using methodology that is explicit, reproducible, and leads to minimum bias. The second most commonly chosen argument against such a thesis was that SRs ‘do not produce enough new knowledge for a dissertation’. The question will serve as a reference point throughout the research an… Research questions are often devised with the use of the PICO structure: Population, Intervention (or Exposure), Control/Comparator, Outcomes. Raising awareness about the importance of SRs in biomedicine, the basic aspects of SR methodology and the status of SRs as original secondary research could contribute to greater acceptance of SRs as potential PhD theses. The 20-item questionnaire, designed specifically for this study by both authors (LP and DS), was first tested for face validity and clarity among five individuals in charge of PhD programs. The PRISMA-P group have identified a list of ‘Preferred reporting items for systematic review and meta-analysis protocols’ (Moher et al. The first step is to formulate a research question. 2010;20(3):319–2. SRs can be instrumental in improving methodological quality of new experiments, providing evidence-based recommendations for research models, reducing avoidable waste, and enabling evidence-based translational research [20]. There are 105 institutions included in the ORPHEUS network. © 2020 BioMed Central Ltd unless otherwise stated. Google Scholar. It fulfills all requirements of the degree in PhD dissertation. Systematic reviews (SRs) are a type of secondary research, which refers to the analysis of data that have already been collected through primary research [1]. Meta-analysis: statistical alchemy for the 21st century. Research that is not necessary harms both the public and patients, because funds are not invested where they are really necessary, and necessary research may not be conducted [17]. 1a, b). Half red and half green dots indicate the five universities with institutions that have opposite rules regarding recognition of a systematic review as a PhD thesis. A systematic review involves several stages and activities, some of which involves planning the review, conducting the review and reporting the review.” Systematic reviews adhere to a strict scientific design based on pre-specified and reproducible methods. They should also be useful if you are simply wanting to conduct an advanced literature search for your undergraduate studies or postgraduate dissertation. Cook DJ, Mulrow CD, Haynes RB.
