Primary or secondary?

The article in the journal is the secondary source.

Explanation:

A research literature review can be constructed by taking information from two types of sources which are grouped as primary sources or secondary sources.

The primary sources include the original research papers, excerpts written by the scientists himself or any other original documents.

Any article published in magazines, newspapers and journals that reflect the original result but do not have the exact words written in the research paper are all secondary sources.
