RESUMO
Review article is an important part of medical journals. It provides readers with the latest progress and cutting-edge ideas of medical research, which is of great interests for medical workers. An excellent review is not a simple literature listing. The author not only needs to summarize the important findings and highlights in the literature, but also needs to make a fair evaluation of the current research situation, deeply analyze the deficiencies and put forward his/her own unique views. The purpose is to enable readers to fully and accurately understand the research progress in this field, and inspire the readers to explore ideas, grasp the future direction and carry out innovative research. This paper will focus on how to improve the writing level of medical literature review in the process of topic selection, literature collection and screening, data analysis and evaluation.
