PubMed is a database of health sciences and biomedical scholarly journal articles. It is one of the top resources to try when looking for primary research articles for an EBM question.
How can I use PubMed?
Search for Articles
Enter a search strategy in the search box on the homepage to begin viewing articles on your topic.
You can limit what type of articles you are seeing by using the Article Type filter on the left-hand side of the screen. This is an easy way to quickly hone in on the top levels of evidence, such as systematic reviews, meta-analyses, and randomized controlled trials. However, not all study designs are an option, so you may have to scan through the full results to find what you are looking for.
Use Clinical Queries
Clinical Queries is a special search interface that you can access from the PubMed homepage under the Find heading.
They have filters that can be applied based on the type of question you are asking, such as Therapy, Diagnosis, Prognosis, or Etiology.
Simply enter your search strategy in the box and select the Question Type filter to view potential Clinical Studies.
