A primary article is a research article that brings forth first-hand results of the original research and is written by author/s who conducted the research studies. Theses articles are providing direct evidence or first hand testimony regarding a particular topic. Following peer assessment, these articles are usually published in scientific journals. A conventional format such as Introduction, Methods, Results, and Discussion. Primary articles improve scientific understanding by introducing new scientific findings in the area of research.
