Meanwhile, the experts could raise their opinions and suggestions about the items. Finally, confirming the included items according to the results of expert consultation and providing the draft for the second round consultation. [Results] According to the results of systematic literature search, complying with the STROBE guideline of observational studies and other procedures of methodological guidelines, we formulated the questionnaire including 45 items. The recovery rate of the questionnaire (specialist active coefficient) was 81.8%. The concentration indexes, including mean, mode and sum scores calculated from experts' opinion were consistency, which indicated a good degree of concentration among experts' opinion. All coefficient of variation (CV) were < 0.3, suggesting coordination degree of experts was better. The results showed that mean scores of 36 items were greater than or equal to 4 points,and 9 items were greater than or equal to 3 points and less than 4 points. The identification about time point of traditional Chinese medicine (TCM) syndrome and constitution classification in TCM were questioned more. [Conclusion] The 36 items were included in the second round survey,and 9 items had the possibility to be included.
