A meta-analysis research paper is a type of scientific study that systematically combines and analyzes the results of multiple individual studies addressing the same question. It is used to synthesize existing research on a topic, identify patterns, resolve inconsistencies, and improve the precision of conclusions. They should be around 8-12 pages.

A systematic review paper is a type of research paper that provides a comprehensive, structured, and transparent summary of all relevant studies on a specific research question. It follows a rigorous methodology to identify, assess, and synthesize evidence from multiple studies, aiming to minimize bias and provide reliable conclusions. They should be around 10-15 pages.

A case series paper is a type of observational study that documents and describes a group of patients with a similar diagnosis or medical condition. Unlike a case report, which focuses on a single individual, a case series includes several cases, typically without a control group. These papers aim to highlight particular aspects of a disease, treatment outcomes, or unusual presentations, offering insights into clinical practice and guiding further research. They should be around 10-15 pages.

Review articles are concise and critical surveys of novel accomplishments in the author’s research field and should bring up the most important current topics or present interpretative and critical accounts, but not simple compilation, on subjects of general interest. The work need not be complete; however, supporting experimental data must be described. They should be around 15 pages.
