Why may secondary manuscripts be developed?

The development of secondary manuscripts is primarily aimed at providing additional insights and emphasizing vital components of a study that may not have been fully explored in the primary manuscript. These secondary works allow authors to delve deeper into specific results or aspects of the research, highlighting findings that have significant implications or require further discussion. This is valuable in disseminating knowledge effectively, as it can offer greater clarity, detail, or context that enhances the reader's understanding of the original study's impact and relevance.

In contrast, summarizing unrelated studies does not serve the purpose of elaborating on the findings of a primary manuscript. Similarly, while expanding findings beyond the original study can be an important aspect of research, it does not directly address the significant aspects that might not be covered in the primary manuscript itself. Finally, disputing the conclusions of a primary manuscript would represent a critical perspective but is not the primary reason for developing secondary manuscripts; instead, the goal is to provide complementarity and enrichment to the original findings.
