CORE--DATA MANAGEMENT AND STATISTICS

该计划中提出的五个科学项目具有很高的 相互关联，因为它们涉及多个不同的集合 来自共同主题组的数据类型。此外，这些医院的病人 这些项目将在几年内得到跟踪。因此，其中许多 计划的具体目标只有在有一个 高效的集中数据管理系统。的具体目标 这一核心是：1)维护计算机化的数据文件以供参考 派生自个别项目和核心，2)进行持续 数据库的质量控制检查，3)提供数据摘要 应要求调查人员，4)提供统计咨询以 调查人员，5)根据需要进行统计分析。全 项目将使用此核心。

The five scientific projects proposed in this programs are highly interconnected since they involve the collection of several different types of data from common subject groups. Furthermore patients in these projects will be followed over several years. Consequently many of these specific aims of the program can only be achieved if there is an efficient system of centralized data management. The specific aims of this core are: 1) To maintain computerized data files for information derived from the individual projects and cores, 2) To conduct ongoing quality control checks of the database, 3) To provide data summaries to investigators upon request, 4) To provide statistical consultation to investigators, 5) To perform statistical analyses as needed. All projects will use this core.
