Objective  To understand the basic evidence-based knowledge mastery  of postgraduates before the course of the network Meta-analysis of Peking University Health Science Center.

Methods  This study focused on graduate students who attended the Evidence Integration and Application: Network Meta-analysis Course from 2021 to 2023. Questionnaires were used to assess students' knowledge of network Meta-Analysis and attitudes related to the course, and comparisons were made between master's and doctoral students using the Kruskal-Wallis H test.

Results  A total of 84 students participated in the survey, including 54 master's students and 30 doctoral students. Students who enrolled in the course had a certain level of competence in literature searching and reading skills before taking the course, with no statistically significant differences between master's and doctoral students (P>0.05). Students had a basic understanding of fundamental course terms, but displayed relative weaknesses in the knowledge of the specific application of Meta-analysis, with proportions ranging from 46.67% to 61.11% of students reporting unfamiliarity with these aspects. Compared to doctoral students, master's students exhibited a reduced comprehension of differences between systematic review and traditional review (P=0.014), and basic steps to implement evidence-based medicine (P<0.001), the differences between the two groups were statistically significant. Graduate students who selected this course generally had initiative and curiosity of learning.

Conclusion  Students who chose this course demonstrate superior literature search and reading abilities, and they are prepared to approach this course with a serious attitude. However, there is still a need to improve their understanding of Meta-analysis related content. The results provide reference of the improvement of the teaching content and model of this course.
