What feature of a professional journal indicates that it provides evidence-based and reliable sources of information?

The feature that indicates a professional journal provides evidence-based and reliable sources of information is that the articles are peer-reviewed. Peer review is a critical process in which experts in the field assess the quality, validity, and originality of research before it is published. This process ensures that only high-quality, rigorously vetted research makes its way into the journal, contributing to the reliability of the information presented. The peer-review system acts as a quality control mechanism that helps maintain academic standards and integrity in scholarly publishing.

Having colorful illustrations, being authored by well-known experts, or covering a broad range of topics does not necessarily guarantee that the information is evidence-based or reliable. These features may enhance the appeal or reach of the journal, but they do not ensure the scientific rigor or validation of the content.
