What is a Systematic Review?
A Systematic Review is a scientific investigation that focuses on a specific question and uses explicit, pre-specified scientific methods to identify, select, assess, and summarize the findings of similar but separate studies.
It may include a quantitative synthesis (meta-analysis), depending on the available data.

- Why are systematic reviews important?
- What’s the difference between a systematic review and a meta-analysis?
- Can you explain the sudden popularity of systematic reviews?
- How can researchers improve the quality of their systematic reviews?
- Systematic reviews often consider “risk of bias”. What does that mean?
- Cochrane focuses on medical research. Do you think systematic reviews have a place in other fields of research?
Systematic review support is available to students, faculty, and staff planning to start a systematic reviews, meta-analysis, scoping reviews or rapid reviews. Calder Librarians are collaborators who can design and manage thorough, complex searches in multiple databases for you.
Systematic review collaboration with a librarian may include:
- Consultations with individuals and teams.
- Helping to define the research question.
- Targeting specific databases and other resources to be searched.
- Identifying database-specific search strategies.
- Conducting literature searches.
- Delivering citations into bibliographic management tools (EndNote, RefWorks, Mendeley).
- Writing the literature search method section for any manuscript.
P: Planning- the methods of the systematic review are generally decided before conducting it.
I: Identifying- searching for studies which match the preset criteria in a systematic manner.
E: Evaluating- sort all retrieved articles (included or excluded) and asses the risk of bias for each included study.
C: Collecting/combining: each study is coded with preset form, either qualitatively or quantitatively synthesize data.
E: Explaining: placed results of synthesis into context, strengths and weaknesses of the studies.
S: Summarizing: report is provides description of methods and results in a clear and transparent manner.

“That which is produced on all levels of government, academics, business, and industry in print and electronic formats, but which is not controlled by commercial publishers” (4th International Conference on Grey Literature 1999). Could be government reports, annual reports, research registries, regulatory documents, evaluation reports, health services research registries, advocacy group documents, news articles, company publications, blogs, emails, tweets, letters, etc. It is unpublished evidence. The purpose of grey literature is to reduce publication bias effect; smaller studies or studies with null or negative findings does not get published readily." From Margaret Foster's, "Pieces of a Systematic Review: What searches beyond the typical databases should be done?" Webinar, March 2, 2017.
Where to find the grey literature?
ClinicalTrials.gov is a registry and results database of publicly and privately supported clinical studies of human participants conducted around the world. Learn more about clinical studies and about this site, including relevant history, policies, and laws. The Web site is maintained by the National Library of Medicine (NLM) at the National Institutes of Health (NIH). Information on ClinicalTrials.gov is provided and updated by the sponsor or principal investigator of the clinical study. Studies are generally submitted to the Web site (that is, registered) when they begin, and the information on the site is updated throughout the study. In some cases, results of the study are submitted after the study ends. This Web site and database of clinical studies is commonly referred to as a "registry and results database." (From the ClinicalTrials.gov website, accessed on April 21, 2017)
WHO International Clinical Trials Registry Platform (ICTRP)
The Clinical Trials Search Portal provides access to a central database containing the trial registration data sets provided by several trials registries around the world. It also provides links to the full original records. To facilitate the unique identification of trials, the Search Portal bridges (groups together) multiple records about the same trial. Registries that report on a weekly basis include: Australian New Zealand Clinical Trials Registry; Chinese Clinical Trial Registry; ClinicalTrials.gov; EU Clinical Trials Register (EU-CTR); ISRCTN; The Netherlands National Trial Register, and others. Please note: This Search Portal is not a clinical trials registry.

These modules use the Cochrane methodology. The principles are useful for conducting any systematic review of interventions.
Structure and learning approach
"Cochrane Interactive Learning consists of 10 modules, each divided in several sections (topics) with one or more pages of content. Each page is built of several bite-size learning units, building knowledge one step at a time. This allows learners to easily navigate through the modules and learn at their own pace.
A variety of formats is used to present the content and reinforce the learning: scrolling web pages, media (including animations, video and audio recordings), interactive exercises, quizzes, worked-out examples, and assessments. Learners can filter the content, mark the favourite pages, and monitor their progress, which allows a personalized, self-directed learning experience."
(from the Cochrane website)
Modules include Writing the Review Protocol, Selecting Studies and Collecting Data, Introduction to Study Quality and Risk of Bias, Interpreting the Findings, and Reporting the Findings. There are new modules on network meta-analysis and health equity in systematic reviews.
The first module, Introduction to Conducting Systematic Reviews, takes approximately 45 minutes.
Users who complete the course or individual modules can download certificates to verify their completion
