Using Boolean Operators

 

Using Limits in Your Search

What are limits and why use them?

Limits are helpful in focusing your search.  Once you've done your initial search you can use some limits to help you narrow your results to a more manageable amount of information.

  • Date:  limit results to a specific time frame
  • Peer review:  limit to only peer-reviewed articles
  • Full text:  find only the articles available in full text  **TIP:  you can request an article that isn't available through Interlibrary Loan
  • Publication type:  limit results to meta analysis, reviews, systematic reviews, research articles, and evidence based practice.

Systematic Reviews & Meta Analysis

What are Systematic Reviews & Meta Analyses?

Systematic Review
"A systematic review attempts to identify, appraise and synthesize all the empirical evidence that meets pre-specified eligibility criteria to answer a given research question"  (The Cochrane Library)

Meta Analysis
Meta analysis is "a statistical synthesis of the numerical results of several trials which all address the same question" (Greenhalgh, 2010, p.121).

Where do I find Systematic Reviews & Meta Analyses?

The Cochrane Library and JBI - Ovid are primary resources for finding meta analysis and systematic reviews.  However they can also be found in PubMed and Health - EBSCO databases.
