With reference to the concept of participants-related core outcome sets（Pa-COS）

this paper brought out new hypothesis that traditional Chinese medicine specific outcome sets（TCM-SOS） should be established based on the characteristics of TCM treatment. TCM-SOS was identified to the effective and safety outcomes related to the specific intervention that were categorized into the non-core outcomes sets

which described the feature about the treatment intervention such as acupuncture

Tuina

and herbal formulae. From the perspective of methodology

the relationship between Pa-COS and TCM-SOS belongs to the dialectical view of commonness and individuality. Pa-COS emphasizes the commonness of outcome indicators in a specific health state

while TCM-SOS highlights the specific effect of certain interventions on a specific health state. In terms of research methods

the former emphasizes the importance and feasibility of outcome indicators for specific health status

while the latter lays emphasis on the specificity and significance of outcomes to reflect the effects of intervention. Taking chronic low back pain as an example

this paper described the research method

process and results of constructing TCM-SOS by using a mixed method research with the goal of "reflecting the characteristics of interventions". To meet the requirements of the minimum reporting of outcome indicators and to address the characteristics of TCM interventions

a new system of outcomes sets should be established and introduced

of which the COS was regarded as the core model for population health condition

while the TCM-SOS as the specific model for TCM intervention feature.
