Clinical Guidelines

Clinical Guidelines provide a summary of existing literature to aid clinicians in diagnosing and treating illness. No experiments are performed or data gathered, and the documents make use of existing literature to draw conclusions.Articles from point-of-care tools like UpToDate or StatPearls are Clinical Guidelines.

"Gather their own data"

Look at the methods section of the article.*

• Did the authors of the article conduct an experiment?
• Did they send out a survey to gather information from a population?
• Did the authors work with human subjects to test a hypothesis?
• Is there any other evidence that the authors designed and conducted an experiment or study that involved some kind of activity other than reading and synthesizing existing research?

*Don't see a methods section? There's a good chance the authors didn't gather their own data.

aka Retrospective Studies

Raw Data Analysis

Primary sources can also take the form of Retrospective Studies. Retrospective Studies involve analyzing existing data (i.e. from a medical records system).This is common for studies that deal with topics that would be unethical to perform experiments to test. (Examples: using existing patient data to chart how diseases spread, or studying data about Sudden Infant Death Syndrome.)
