In recent years, the Data Monitoring Committee (DMC) has played a crucial role in clinical trials, especially in protecting the safety of subjects and ensuring the integrity and credibility of trial results. With the rise of real-world study, the application of DMC in real-world settings has also gradually attracted attention. In this paper, the application of DMC in real-world study is discussed, the functions of DMC in safety monitoring, efficacy monitoring, research operation quality monitoring, and recommendations for modifications of research designs are analyzed, and the differences in DMC's functions between real-world study and randomized controlled trials are compared. Through case analysis, this paper summarizes the best practices of DMC in real-world study, so as to provide references for future related research.
