Which type of manuscript is typically in greater detail regarding original research?

The primary manuscript is the correct choice because it is designed to present original research findings and includes detailed methodologies, analyses, and results related to a specific study. In a primary manuscript, authors provide a comprehensive overview of their research, explaining the objectives, experimental design, data collection, and interpretation of their results. This format allows for an in-depth exploration of the research question and is essential for the scientific community to scrutinize and build upon the findings.

In contrast, a secondary manuscript summarizes or synthesizes existing information rather than presenting new original data. A systematic review, while detailed, focuses on evaluating and summarizing previously published studies through a specific methodology, rather than detailing new research findings. A narrative review, on the other hand, offers a more subjective summary of literature without the structured approach of a systematic review, lacking the depth of original research data.

The primary manuscript stands out as the definitive type of manuscript that delves deeply into new research information, making it the most comprehensive choice in terms of detailing original studies.
