Writing a Literature Review: For Researchers: Systematic Literature Reviews

Kia ora! This is a guide for writing literature reviews for researchers. This guide provides quick links to resources and help, to support your research.

A systematic review is a tightly structured literature review that focuses on a topic with strict research parameters. The methodology used to collect research has to be consistent in order to reduce misinterpretation and misrepresentation of the data.

First Steps

  • Use referencing software e.g. EndNote or Zotero
  • Create a folder with a page for each database
  • Note the search strategy for each database
  • Note all search terms, note the key words for each search
  • Note the number of references found, note the date/s of search
  • Note the number of results when words added or returned to search
  • In databases, look at their help pages for " " search strategies or limits
  • Note any limits used
  • Use filters e.g. exclude reviews
  • Note any filters used
  • Save search strategy online so you can rerun your search
  • Write up in a narrative way but use flow charts and put results in a table

What is PRISMA?

PRISMA is an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses. PRISMA focuses on the reporting of reviews evaluating randomized trials but can also be used as a basis for reporting systematic reviews of other types of research, particularly evaluations of interventions. Check the PRISMA website for more information. 

What is meta-analysis?

Meta-analysis uses statistical methods to combine the results of a systematic literature review. It is considered original work. Booth et al. (2016), define meta-analysis as the

Process of combining statistically quantitative studies that have measured the same effect using similar methods and a common outcome measure.

Clarification of Terminology

The term “Systematic Literature Review” is a specific type of review which involves, among other things, designing a specific search strategy, and then conducting it in one or several databases (not Library Search), applying specified inclusion and exclusion criteria to the items found, and reporting on it. If you have been advised to conduct a systematic review it would pay to clarify this, as it may be that you just need to perform a literature search in a systematic manner, rather than a full Systematic Literature Review.
