This Course Guide will help you find credible information in library databases on the symptoms, diagnosis, treatment, history and epidemiology of a disease.

Peer-reviewed journal articles

Peer-reviewed journal articles (also called scholarly or science journal articles) are great sources for finding the most current information about the symptoms, diagnosis, treatment, epidemiology, and history of a disease.

How to read a peer-reviewed journal article

Peer-reviewed articles are usually broken into obvious sections. Most peer-reviewed articles will have these sections.

  • Abstract: definitely read it. An abstract is a brief summary of all the sections.
  • Introduction: read it. The medical team will describe the aspect of the disease they are trying to understand, or treat.
  • Literature review: definitely read it. If there's any history of the disease to be gleaned, it will be here.
  • Methodology: skip it until you're admitted to medical school.
  • Results: skip it. Be aware that later you may discover a couple of the graphs work well in your final presentation.
  • Discussion: read it. The medical team will describe their findings about the disease.
  • Conclusion: read it. The medical team will describe how their findings fit in the bigger picture of the disease.
  • References/Works Cited: skip them until you get to medical school.
