Original Research Articles vs. Review Articles

Original research articles

Authors of original research articles propose a hypothesis and then prove or disprove it with their chosen method.

The article reports the results of this experiment or study. Original research articles will usually feature the following:

  • Introduction - this usually features a statement of the problem and a review of earlier research
  • Method - a description of the experiment and how data was interpreted
  • Results - what actually happened when they did the experiment
  • Discussion - Was the hypothesis proven or disproved?  What are some avenues for further research?

Review articles

In review articles the authors discuss the findings of many original research articles written on the same topic. Review articles do not usually have methods or results sections as there is no new study being done. The review is a means to report on the current state of research in an area based on analyzing the existing original research articles regarding that area.

Examples

To help you distinguish between these two types of peer reviewed science articles, I have found an example of each.

Example of primary research article:

Nelms, S. E., Galloway, T. S., Godley, B. J., Jarvis, D. S., & Lindeque, P. K. (2018). Investigating microplastic trophic transfer in marine top predators. Environmental Pollution, 238, 999–1007. https://doi.org/10.1016/j.envpol.2018.02.016

Example of review article:

Zhang, H. (2017). Transport of microplastics in coastal seas. Estuarine, Coastal and Shelf Science, 199, 74–86. https://doi.org/10.1016/j.ecss.2017.09.032

Practice your research skills! Can you tell if these articles are primary original research articles or reviews?
