What is a Systematic Review?
What is a Systematic Review?
A systematic review is a literature review that gathers all of the available evidence matching pre-specified eligibility criteria to answer a specific research question. It uses explicit, systematic methods, documented in a protocol, to minimize bias, provide reliable findings, and inform decision-making. ¹ ²
There are many types of literature reviews.
Before beginning a systematic review, consider whether it is the best type of review for your question, goals, and resources. The table below compares a few different types of reviews to help you decide which is best for you.
| Systematic Review | Scoping Review | Systematized Review |
|---|---|---|
| Conducted for Publication | Conducted for Publication | Conducted for Assignment, Thesis, or (Possibly) Publication |
| Protocol Required | Protocol Required | No Protocol Required |
| Focused Research Question | Broad Research Question | Either |
| Focused Inclusion & Exclusion Criteria | Broad Inclusion & Exclusion Criteria | Either |
| Requires Large Team | Requires Small Team | Usually 1-2 People |

How can the library help?
The average systematic review takes 1,168 hours to complete.¹
A librarian can help you speed up the process.
Systematic reviews follow established guidelines and best practices to produce high-quality research. Librarian involvement in systematic reviews is based on two levels. In Tier 1, the librarian will collaborate with researchers in a consultative manner. In Tier 2, the librarian will be an active member of your research team and co-author on your review. Roles and expectations of librarians vary based on the level of involvement desired. Examples of these differences are outlined in the table below.

Software engineering
- Guidelines for Performing Systematic Literature Reviews in Software EngineeringThe objective of this report is to propose comprehensive guidelines for systematic literature reviews appropriate for software engineering researchers, including PhD students.
Evidence-Based Software Engineering and Systematic Reviews by Call Number: QA76.758 .K58 2016 (Science Annex)ISBN: 9781482228656Publication Date: 2015-11-05In the decade since the idea of adapting the evidence-based paradigm for software engineering was first proposed, it has become a major tool of empirical software engineering. Evidence-Based Software Engineering and Systematic Reviews provides a clear introduction to the use of an evidence-based model for software engineering research and practice. The book explains the roles of primary studies (experiments, surveys, case studies) as elements of an over-arching evidence model, rather than as disjointed elements in the empirical spectrum. Supplying readers with a clear understanding of empirical software engineering best practices, it provides up-to-date guidance on how to conduct secondary studies in software engineering--replacing the existing 2004 and 2007 technical reports. The book is divided into three parts. The first part discusses the nature of evidence and the evidence-based practices centered on a systematic review, both in general and as applying to software engineering. The second part examines the different elements that provide inputs to a systematic review (usually considered as forming a secondary study), especially the main forms of primary empirical study currently used in software engineering. The final part provides practical guidance on how to conduct systematic reviews (the guidelines), drawing together accumulated experiences to guide researchers and students in planning and conducting their own studies. The book includes an extensive glossary and an appendix that provides a catalogue of reviews that may be useful for practice and teaching.
Sport, Exercise, & Nutrition
Conducting Systematic Reviews in Sport, Exercise, and Physical Activity by ISBN: 9783030122621Publication Date: 2019-09-11This book offers a conceptual and practical guide to the systematic review process and its application to sport, exercise, and physical activity research. It begins by describing what systematic reviews are and why they assist scientists and practitioners. Providing step-by-step instructions the author leads readers through the process, including generation of suitable review questions; development and implementation of search strategies; data extraction and analysis; theoretical interpretation; and result dissemination. Conducting Systematic Reviews in Sport, Exercise, and Physical Activity clarifies several common misunderstandings including the difference between qualitative systematic reviews and meta-analyses . Each chapter begins with a set of learning objectives focused on practical application, illustrated with examples from reviews published within the sport, exercise, and physical activity fields. Once a reader has completed all the learning activities along the way, they will have designed a systematic review and have written a protocol ready for registration. The book ends with a collection of advice from internationally regarded scientists with substantial experience in systematic reviews.- Application of systematic review methodology to the field of nutrition byPublication Date: 2009
