Published research, also referred to as published studies or research, can be hard to follow. These links from the National Library of Medicine can simplify the way you read a published study and help you find out what information they contain, how to read them and how to understand the medical terminology used in many studies.

Tips for reading research studies: 

Studies are usually divided by abstract, introduction, methods, results/findings and discussion/conclusion. Consider these questions when reading a research study:

  • Are you or your family member like the people who are studied? If you're not, then a comparison may not be helpful.
  • How large is the study? Bigger is often better.
  • Does the study have standards for comparison: a control group that does not receive the experimental intervention compared to the experimental group that does?
  • Is the study “cross-sectional,” meaning that it was correlated among groups of participants at a single point in time or “longitudinal,” meaning that it followed individuals over time?
  • What did the research find and is it relevant to you?
  • Do the conclusions suggest more research is needed?

PubMed is a free searchable database from the National Library of Medicine in Bethesda, Maryland. It includes millions of citations from medical and science journals back to 1948. It is where peer-reviewed research (research that has been reviewed and accepted by experts in a field of study) is collected and indexed. Most citations have abstracts (summaries of research) that provide information on what the research study is about. In some cases, the full text of the study on Alzheimer's disease and other topics is available. 

Tips for searching PubMed:

  • PubMed Help: to learn how to search, get a full-text article, save your searches, and make the best use of the database.
  • Can't think of the search term? Use the MeSh Database of controlled vocabulary, which is used to index articles in online databases. It consists of preselected words and phrases that describe the research.
  • Combine medical terms in a string: Alzheimer's disease anesthesia.
  • Limit by year, full text and more options through Advanced Search.
  • Need more information? Ask a Librarian.
