Our results can be used to create strategies that will enhance acceptance of SRs among graduate education program directors. 2007;7:10. P I C O; Population or Problem: Intervention or Exposure: Comparison: Outcome: What are the characteristics of the P opulation or patient?. PubMed Central The funder had no role in the design of this study or its execution and data interpretation. A requirement that a PhD candidate should be the first author on a manuscript(s) that constitutes a PhD thesis was reported in 82% (n = 64) of the graduate programs. 2008;105(20):380–3. The aim of searching the literature is to produce an inclusive list of relevant research studies from which to select the studies included in the review. California Privacy Statement, Lancet. The graduate program and the mentor need to ensure that a PhD candidate receives sufficient knowledge to complete the proposed thesis topic. The discussion section should also be clearly ordered. A protocol should be created at the start of the systematic review project. 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. 2013;35(7):609. Part of This section covers the number of studies found, how many excluded, details of study range and characteristics, study quality, and so on. Four respondents from three institutions indicated that empty SRs are accepted as a PhD thesis. Strengths and weaknesses of the studies included in the review are considered. If the purpose of a review is to make justifiable evidence claims, then it should be systematic, as a systematic review uses rigorous explicit methods. 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. 1995;48(1):71–9. However, only 20% of participants expressed a personal opinion that SRs meet the criteria for a PhD thesis. Organisation for PhD Education in Biomedicine and Health Sciences in the European System (ORPHEUS). Syst Rev 6, 253 (2017). IP-2014-09-7672 ‘Professionalism in Health Care’. The most commonly specified databases were Web of Science (41%; n = 35) and MEDLINE/PubMed (13%; n = 11), followed by Science Citation Index, Scopus, Current Contents, a combination of several databases or, in two cases, a combination of journals from a list defined by some governing body. The datasets used and/or analysed for the current study are available from the corresponding author on reasonable request. CAS In our study, 80% of the participants reported negative attitudes, and more than half of the respondents agreed with a statement that SRs are ‘not a result of the candidate’s independent work since systematic reviews tend to be conducted by a team’. While it makes sense to include such a SR as a part of the thesis to indicate lack of evidence in a certain field, it is highly unlikely that an entire thesis can be based on an empty SR, without a single included study. Google Scholar. In 60% (n = 52) of the graduate programs, the quality of the journals where a PhD candidate has to publish research manuscripts as a part of a PhD thesis was defined by the database in which these journals are indexed. Such tables typically include the population studied, interventions and outcomes. http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/, https://doi.org/10.1186/s13643-017-0653-x. J Clin Epidemiol. Dissertation examples Listed below are some of the best examples of research projects and dissertations from undergraduate and taught postgraduate students at the University of Leeds We have not been able to gather examples from all schools. 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. Systematic reviews (SRs) are a type of secondary research, which refers to the analysis of data that have already been collected through primary research . The next paragraph describes limitations of studies included and of the review process. Systematic reviews (SRs) have been proposed as a type of research methodology that should be acceptable for a graduate research thesis. Dtsch. 2010;20(3):319–2. Check your syntax! The ethics committee of the University of Split School of Medicine approved this study, which formed part of the Croatian Science Foundation grant no. The questionnaire included questions about their PhD program; whether PhD candidates are required to publish manuscript(s) before thesis defence; the minimum number of required manuscripts for defending a PhD thesis; the authorship requirements for a PhD candidate with regard to published manuscript(s); whether there is a requirement for a PhD candidate to publish manuscript(s) in journals indexed in certain databases or journals of certain quality, and how the quality is defined; the description about other requirements for defending a PhD thesis; whether a SR partly or fully meets requirements for approval of a PhD thesis in their graduate program; what are the rules related to the use of a SR as the basis for a PhD thesis; and the number of PhD theses based on SRs relative to other types of research methods.

This research was funded by the Croatian Science Foundation, grant no. Inclusion and exclusion criteria should also be determined at this stage. In most of the programs (37%; n = 22), the number of required manuscripts was three or more. The majority of the editors indicated that they do think that SRs are original scientific contributions (71%) and almost all journals (93%) published SRs. PubMed Central Even in the same country, there may be different models and expectations for a PhD in different higher education institutions. The association between participants’ results on the knowledge test and attitudes towards SRs was tested using a point-biserial correlation; this revealed that lack of knowledge was not correlated with negative attitudes towards SRs (r ILAR J. 1 Title Page The title page must include the full title of the dissertation, the degree for which it is submitted, the candidate’s name, the year and the date (see example in course handbook appendices). Development of AMSTAR: a measurement tool to assess the methodological quality of systematic reviews. The methods of the review are drawn from the Cochrane Handbook for Systematic Reviews of Interventions (version 5.1.0), which is the official 2012;7(5):e35732. Available at: http://www.orpheus-med.org/. Med Prim Care. ORPHEUS approved the use of their mailing list for the purpose of this study. However, most of the participants had negative attitudes about such a model for a PhD thesis, and most had insufficient knowledge about the basic aspects of SR methodology. Marusic A, Sambunjak D, Jeroncic A, Malicki M, Marusic M. No health research without education for research—experience from an integrated course in undergraduate medical curriculum. Survey responses were entered into a spreadsheet, checked by both authors and analysed using Microsoft Excel (Microsoft Inc., Redmond, WA, USA). A copy of this completed form will be available via the intranet to help others carrying out reviews in the future and to avoid duplicating work already undertaken in the Centre. 2009;6(7):e1000100. In 1995, Feinstein suggested that such studies are ‘statistical alchemy for the 21st century’ and that a meta-analysis removes or destructs ‘scientific requirements that have been so carefully developed and established during the 19th and 20th centuries’ . Systematic reviews assess as much as possible of the available research in the area of concern. 2013;2(1):9–14. Biondi-Zoccai et al. A PhD candidate can prepare a Cochrane SR as a part of the PhD thesis, yielding a high-impact publication . Evidence mapping 4. The aim of this study was to analyse whether PhD theses in European biomedical graduate programs can be partly or entirely based on SRs. What is the P roblem, condition or disease you are interested in?. Article 2014;55(3):427–37. Acommon type of submission at any Journal is a review of the published information related to a topic.These are often returned to their authors without review, usually because they are literature reviews rather than systematic reviews.

Springer Nature. Systematic reviews, scoping reviews, rapid reviews, meta-analyses, realist reviews, living systematic reviews, narrative syntheses, practice guidelines, among others, are all forms of knowledge syntheses. The findings of the studies are summarised, and conclusions indicated. 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. The survey was administered via Survey Monkey (Portland, OR, USA). The most common rule was that a SR can be one publication among others within a PhD thesis. 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 . 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. They provide reliable estimates about the effects of interventions. Bibliographic databases including Pubmed, Medline, the Cochrane Library and Embase (for healthcare) can be used. 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. 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. Quantifying heterogeneity in a meta-analysis. Refers to any combination of methods where one significant component is a literature review (usually systematic). Research questions are often devised with the use of the PICO structure: Population, Intervention (or Exposure), Control/Comparator, Outcomes. Liberati A, Altman DG, Tetzlaff J, Mulrow C, Gotzsche PC, Ioannidis JP, Clarke M, Devereaux PJ, Kleijnen J, Moher D. The PRISMA statement for reporting systematic reviews and meta-analyses of studies that evaluate health care interventions: explanation and elaboration. On the other hand, systematic literature review is a well-planned review to answer specific research questions using a systematic and explicit methodology to identify, select, and critically evaluate results of the studies included in the literature review. In most cases, the missing data were related to knowledge about SR methodology. © 2020 BioMed Central Ltd unless otherwise stated. The question should be clearly focussed, neither too narrow nor too broad. Most of the respondents agreed that narrative or critical/discursive literature reviews preceding clinical studies planned as part of a dissertation should be replaced with systematic reviews (Table 2). Formal training in skills related to SRs and research synthesis methods [15, 16], as well as establishing research collaborations with researchers experienced in this methodology, could alleviate this concern. There are SRs with tens or hundreds of included studies, and some of them not only include meta-analyses, but also network meta-analyses, which are highly sophisticated statistical methods. That study also highlighted that the definition of original research may be a grey area . The second most commonly chosen argument against such a thesis was that SRs ‘do not produce enough new knowledge for a dissertation’. Baethge C. Publish together or perish: the increasing number of authors per article in academic journals is the consequence of a changing scientific culture. Indeed, it has been suggested that SRs as ‘secondary research’ are different than ‘primary or original research’, implying that they are inferior and lacking in novelty and methodological rigour as compared to studies that are considered primary research. Including student tips and advice. 2014;14(2):102–5. This opinion is surprising since other types of research are also conducted within a team, and single authorship is very rare in publications that are published within a PhD thesis. In four programs, there was no formal policy on this matter, but there was a strong expectation that the student will have contributed substantially to several manuscripts in peer-reviewed journals. PubMed CAS The question will serve as a reference point throughout the research an… Descriptive data are presented as frequencies and percentages. On the contrary, the mean number of authors of research manuscripts is continuously increasing . The results should be set out logically.

Further studies in this field could provide better insight into attitudes related to SRs as graduate theses and explore interventions that can be used to change negative attitudes and improve knowledge of SRs among decision-makers in graduate education. Aveyard and Sharp defined SRs as ‘original empirical research’ because they ‘review, evaluate and synthesise all the available primary data, which can be either quantitative or qualitative’ . 1997;126(5):376–80.

All respondents consented to participate in the study. “ A systematic review is a means for evaluating and interpreting all the available research that is relevant to a particular research question, topic area or a phenomenon of interest. A systematic review involves several stages and activities, some of which involves planning the review, conducting the review and reporting the review.” Define inclusion and exclusion criteria. Int. Reference lists of articles are useful for finding new areas to investigate, as can handsearching of journals. Article PubMed Central 1a, b). The distinction between a systematic literature review and a literature review can often be confusing. pointed out that the main criteria to judge a SR should be its novelty and usefulness, and not whether it is original/primary or secondary research .
