The hierarchical structure of midterm evaluation quantitative indicators in TCM clinical research was established according to the basic ideas of analytic hierarchy process（ AHP） and the purpose and requirements of midterm evaluation. The midterm evaluation quantitative indicators were determined according to expert advice and joint inspection indicators. The multiplication method of combining weights was used to determine the subjective weights of indicators. The quantitative indicators were composed of 10 items such as included cases / total cases

recycling records of study drugs / drug-receiving records of subjects

unreasonable altered medical records

origin of physical and chemical testing

verifying the authenticity of subjects

signing informed consent

reporting electronic research data

completing the electronic data within a specified time window

checking the consistency of electronic case report forms and key indicators in medical record research and two-stage inspection. The normalized weights of these 10 items mentioned above were 0. 131

0. 069

0. 085

0. 085

0. 077

0. 300

0. 054

0. 054

0. 054 and 0. 092 in turn.
