[Enlightenments of DITTO framework and its application for setting up mock acupuncture in clinical research]

How to set up a placebo control scientifically and effectively is a problem in clinical research on acupuncture therapy. In 2020, the UK National Institute of Health Research established a standardized methodological framework DITTO, that is, "Deconstruct""Identify""Take out""Think" and "Optimize" to standardize the setting of invasive console-control intervention. Acupuncture therapy theoretically belongs to the category of invasive therapeutic intervention, and the percutaneous puncture therapy was also considered when the DITTO framework was developed. Therefore, this framework can be applied to clinical research of acupuncture, and may provide a reference for the appropriate setting of simulated acupuncture. In this article, we introduce the formulation process and main contents of the DITTO framework, and analyze the adjustments needed to be made and possible problems encountered in the application of each part of the framework in acupuncture clinical research through medical cases. The DITTO framework can guide and standardize the design of mock acupuncture control in acupuncture clinical research to a certain extent, which is conducive to finding a more suitable implementation method of mock acupuncture, thus promoting the improvement of the quality of acupuncture clinical research. However, because there is no precedent in the field of acupuncture in traditional Chinese medicine, further research is needed in the future practical application so that it can be better combined with the characteristics of acupuncture and the purpose of clinical research.
