A review article is a type of academic paper that summarizes and analyzes existing research on a specific topic. Unlike original research articles, which present new findings, review articles compile and evaluate the results of multiple studies to provide a comprehensive overview. They help readers understand the current state of knowledge and identify gaps in research. These articles are commonly found in scientific journals and are valuable resources for researchers, students, and professionals. By synthesizing information from various sources, review articles can highlight trends, controversies, and future directions in fields such as medicine, psychology, or environmental science.
