Research to standardize the central secretariat system in the collaborative epidemiological studies

为促进流行病学合作研究中中央书记处系统的规范化，对中央书记处进行了访谈。中央秘书处的作用可分为秘书处内部的沟通、研究的实施、整个研究系统的运作、研究站点的管理等。这些事项的必要性取决于秘书处和场址的情况，并可分为最低要求、良好做法和个案事项。

To contribute to the standardization of the central secretariat system in the collaborative epidemiological studies, interviews about the central secretariat were carried out. The roles of the central secretariat could be classified into communication in the secretariat, implementation of research, operation of the entire system of research, administration of the research sites, and so on. The necessity of such matters was depending on the situation of the secretariat and sites, and was able to classify into minimum requirement, good practice, and case-by-case matters.
