(From Research Skills Team Canvas course: Literature Searching for Researchers - requires University of Birmingham login).
The Cochrane Interactive Learning Resource is available to University of Birmingham members (or others with an institutional subscription). This is a valuable learning tool which explores the systematic review process in more detail.
The Cochrane Foundation has a very detailed online handbook, Cochrane Handbook for Systematic Reviews of Interventions (Higgins et al., 2022). This is aimed at authors preparing Cochrane Systematic Reviews*.
Chapters include, for example:
As of August 2023, the Cochrane Foundation announced updates and "some major changes" to its processes (Cochrane Foundation, 2023).
If you are looking for help or information about statistical software related to data extraction, such as SPSS or NVivo, see the University of Birmingham Digital Skills (UoB) page or the Mathematics Support Centre information on Statistics Resources. University of Birmingham members and others with institutional access can access video learning materials on the above on LinkedIn Learning.
Dalhousie University Libraries' Systematic Reviews guide has a section on Data Extraction.
Software can be invaluable in storing and managing references from multiple sources and citing these in documents. At the University of Birmingham, the web-based EndNote Online is supported for undergraduate (UG) and taught postgraduate (PGT) students. The separate, downloadable EndNote Desktop programme is supported for doctoral (PhD), post-doctoral and other academic researchers and staff.
A thorough literature search using a range of bibliographic databases – and grey literature if required - will reduce any perceived risk of bias in studies selected for a Review.
Further information and tools to minimize or assess Risk of Bias can be found for example on the following:
Students are advised to discuss these tools directly with their tutor(s) if required to use them.
You may find that specific, specialised software tools exist that help with systematic reviews but they are not always available at the University of Birmingham. Such tools may have some limited free use but full access is dependent on institutional or School subscription. They are generally aimed at those studying at PhD level and above in subject areas such as Medicine.
For example: Covidence* and Rayyan. The Cochrane Foundation also has information on GRADE and RevMan**. Another tool is EPPI Reviewer. These systematic review management tools are aimed more at the management of research traced through literature searches in the course of a systematic review, and the evaluation and synthesis processes, including viewing by other members of research teams. Covidence and RevMan are available for use via Library Services / FindIt@Bham (see below). Students are advised to speak with their tutors for guidance on use, and to consult the supplier support information.
