Finding evidence synthesis and primary research

 

When writing a literature review or summaries for CBLs or PBLs, it is best to use current synthesis evidence or primary research articles (last five years).  These are the references for your end summary or projects that have been informed by your initial background research.  

When searching, it is best to start by finding any synthesis evidence that covers the topic.  Synthesis evidence attempts to summarize the body of primary research to identify the trend of evidence (or lack thereof) and qualitatively or quantitatively summarize primary research.  The approach is less biased and more transparent than narrative reviews (or expert opinion) and undergoes varying degrees of rigor to reduce bias.
