Explain search

Filter explanation

We have created a colour-coded hierarchy of evidence, based on the various categories used in TRIP. The highest level of evidence is indicated by the colour green and corresponds to the categories 'Evidence Based Synopses', 'Systematic Reviews' and 'Guidelines'.  Different categories are assigned different colours. 

When carrying out a search of TRIP all content is searched.  However, you can easil restrict yor search to a given level of evidence using the slider.  If you only want the highest level of evidence you would move the slider over to the left-hand side.  The further to the left the slider is moved the more lower evidence material is removed from the search results. NOTE: This may remove results more pertinent to the search (but are of a lower evidence level).

 

 

Primary Research - An explanation

While most of the categories are fairly self-explanatory the division in primary research requires further explanation:

  • Core primary research - Content from the big 5 internal medicine journals (NEJM, JAMA, Lancet, BMJ and Annals of Internal Medicine) and from EvidenceUpdates, the wonderful collaboration between the BMJ and McMaster University's Health Information Research Unit (this rates articles from over 130 journals).
  • Extended primary research - Content from a 'core' set of 300 journals identified using a combination of impact factor and expert advice.
