Here are some common characteristics of primary research articles

  • Author(s) present a new set of findings from original research after conducting an original experiment
  • A primary research article typically contains the following sections: Methods (and Materials), Results (with charts, graphs, etc), Discussion.


Example of Primary Research Article:

Fermentation and quality of yellow pigments from golden brown rice solid culture by a selected Monascus mutant.


Here are some common characteristics of review articles:

  • Author(s) analyze and summarize existing research
  • Author(s) did NOT do original research. They are summarizing work of others.
  • Often focus on a general topic (such as breast cancer treatment) and bring together all relevant, useful articles on that topic in one review article.
  • Do not contain sections such as Methods (and Materials), Results because they did not do any original research!


Example of Review Article:

PDE5 inhibitors as therapeutics for heart disease, diabetes and cancer.
