Objective  The basic terms of the technical specifications for case-control studies in the field of traditional Chinese medicine (TCM) are formed by expert consensus methods, in order to develop detailed texts of the technical specifications. Methods  According to the process of international guidelines, a total of 44 experts participated in the Delphi survey. Results  The three rounds of questionnaire response rates were 73.3%, 86.4%, and 86.8%, respectively. The experts' authority coefficients were 0.82, 0.85, and 0.86, respectively; and the expert opinion coordination coefficients were 0.356, 0.349, and 0.422, respectively. Expert enthusiasm, authority, opinion centralization, and degree of coordination were relatively high. There were many opinions raised in the expert consensuses on how to measure TCM syndrome, TCM constitution, the time point of measurement and the selection of new cases. Conclusion  The case-control studies in TCM field should pay more attention to the characteristics of TCM. The draft of technical specification involves the study design and reporting, which can improve the methodological and reporting quality of case-control studies.
