The EBM Process: Searching for the Evidence
Special Considerations

If you find a high quality but older systematic review, it is a good idea to then look for individual RCTs or clinical trials that may have been published since the systematic review.

• In systematic reviews, an ending date of their search is usually included.
  
• Search from ending date of the search used for the systematic review forward in time to see if new RCTs have been published.
  
• Do not confuse the publication date of the systematic review with the ending date of the Author's search!!!
