Integrative Biology: Literature Reviews

What is a scientific literature review?

Not to be confused with a book review, a literature review surveys scholarly articles, books and other sources (e.g. dissertations, conference proceedings) relevant to a particular issue, area of research, or theory, providing a description, summary, and critical evaluation of each work. The purpose is to offer an overview of significant literature published on a topic.

Systematic reviews are reviews of high-quality randomized controlled trials often crucial to evidence-based medicine. Systematic reviews are common to all sciences where data are collected, published in the literature, and an assessment of methodological quality for a precisely defined subject would be helpful.

Ten Steps for Writing a Literature Review:

1. Define a topic and audience:
    must be interesting to you
    an important aspect of the field
    a well-defined issue

2. Search and Re-Search the Literature:

  • keep track of databases and search items
  • keep a list of papers and pdfs,
  • use a management system: Refworks, EndNote, Mendeley
  • define criteria for exclusion
  • use reviews

3. Take NOTES while reading

4. Choose the type of review to write:

  • Mini-review: shorter in length, cover a specific time frame, or narrow subject area
  • Full review: longer, deeper coverage includes details.
  • Descriptive: focuses on methodology, findings, interpretation
  • Integrative: attempt to find common ideas and concepts.

5. Keep the review focused, but broad interest. (could discuss other disciplines affected)

6. Be Critical and consistent: 
A reader should have an idea of
 - The major achievements in the reviewed field.
 - The areas of debate.
 - The outstanding research questions.

7. Find a logical structure.

It can be helpful to use a mind-map to draw a conceptual scheme of the review.

8. Make use of feedback. Can be peer-reviewed or someone reading a draft.

9. Include your own relevant research but be objective.

10. Be Up-to-date, do not forget older studies.

AVOID these traps:

  • Trying to read everything: try to read the most relevant work instead.
  • Reading not writing: writing is a way of thinking, - write many drafts.
  • Reminder: Review papers can have abstracts and illustrations.
  • Failing to keep bibliographic information: remember that you will be writing a page entitled “References” at some point.
  • Organizing your review chronologically: Organize your paper by ideas.

Literature Reviews: Standards

PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses. It is an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses

Cochran: Cochrane Reviews are seen as exemplifying best practice in the quality of both their conduct and reporting. To maintain this position we need to improve and maintain the quality of our output as standards and expectations for systematic reviews increase generally; we also need to ens Cochrane Review Groups (CRGs) and all reviews. To this end we have undertaken within The Cochrane Collaboration to define Methodological Expectations for Cochrane Intervention Reviews (MECIR).
